Review: Koh-i-Noor Polycolor, Prismacolor & Spectrum Noir Colour Blend Pencils

When I first got my hands on the Koh-I-Noor Polycolor pencils, it was under the mistaken belief that they were oil based pencils similar to Faber Castell Polychromos pencils (but much cheaper), there are several YouTube videos and tutorials out there that compare polycolor with polychromos which started me off on the wrong path. But as I worked with the pencils and did further research, I discovered that Koh-I-Noor Polycolor pencils are in actual fact wax based, they do have an oily coating to help improve the performance of the pencil though, I put two and two together after reading the product description of the pencils on the Koh-I-Noor website: -

"The key components of POLYCOLOR professional coloured pencils are rich, top quality with perfectly dispersed pigments, carefully selected and purchased from renowned producers around the world. Their light permanency and dosed concentration also influence the final result and durability of the artwork. Therefore, a high concentration of pigment dosing has been prescribed for this product in its entire colour range. The final product is resistant to water thanks to the oily treatment.

This gives our coloured pencils, along with the addition of binders and other additives, an unsurpassable ability to make a unique stroke on paper or another medium. The pencils contain a set of unique components which ensure a convenient, full colour stroke without the necessity of high pressure. This handy feature is enhanced by the preparation of pastels in special oils. Thanks to the diameter of the lead, 3.8 mm, POLYCOLOR coloured pencils provide excellent artistic value to any user. Noble wood, from which the pencils are made, allows easy sharpening." So a better comparison for the Polycolor would be Prismacolor and Spectrum Noir Colour Blend, two wax based pencil brands that are available for sale in the UK, which is good really as I own a set of 24 Prismacolor Pencils, and a set of SN Colour Blend but only about 8 Polychromos, so I can do a few test swatches to share.

Sanford Prismacolor have been around for a while they were first made by Berol back in 1938, then in 1995 the Newell Company joined forces with Berol and merged to become a branch of the Sanford Corporation. Prismacolor are marketed as artist grade premium colour pencils, and have 150 colours in their pencil rainbow. They are sold in sets and come in tins with plastic trays inside the tin that holds the pencils. A set of 72 can be picked up on Amazon for less that £47.00, and you can buy the colours individually for around £1.50 - £1.90 each. The leads in the Prismacolor pencils are 3.8mm and the barrel has a diameter of 8mm, as of today I haven't been able to discover which wood the barrels of Prismacolor pencils are made from, if I do I'll add the info to this post. I do know that there has been a lot of problems with the Prismacolor since the company moved the manufacturing of them to Mexico several years ago and they have fallen from arty favour a little over the past few years.

Spectrum Noir Colour Blend pencils are part of the Crafters Companion family of crafting products and have 144 colours in their rainbow. They only come is sets of 12 and 24 ranging in price from £15 to £25 a set, you can pick up sale and bundle bargains, but if a particular colour runs out, you have to buy another set because they don't currently sell the pencils individually. The lead in the ColourBlend pencils is 4mm and the barrel has a diameter of 8mm, the barrels are made from Californian Cedarwood.

Koh-I-Noor Polycolor Pencils have 92 colours in their rainbow (as of May 2019) 72 of which are available in the coloured sets, plus Koh-I-Noor do a couple of sets of greys and brown tones and some of the colours in those sets (but not all) aren't in the coloured bundles, because of this unless you don't already have the duplicate colours already it may be better to buy the additional ones open stock rather than in the 12 sets.

I picked up the 36 set for just over £18 off Amazon when they were on special offer, a 72 set on Amazon is currently £39.96 marked down from £90. The lead in the Polycolor pencils is 3.8mm the same as Prismacolor and the barrel has a diameter of 7mm and is made from Noble Fir.

A lot of reviews for Koh-I-Noor Polycolor pencils say that they are not available open stock, meaning you can buy a single pencil colour instead of a whole set. However, I have found them available for 83p each from Cult Pens, and there are a few other places in the UK that you can find them open stock, that said I like Cult Pens, they are one of the cheapest places online in the UK for brands like Copic Ciao and Polychromos and they have the cheapest prices and a fast and reliable service. The Cult Pens page linked to above has a drop down that lists all 92 Polycolor colours by number and colour name. The sets that come in boxes only have the numbers on, but open stock pencils have the number and colour on them apparently, although I've seen some examples that don't so until I order some more I won't know for certain.

Speaking of colours, for some reason known only to the manufacturers, the colours on Koh-I-Noor's Polycolor Colour Chart run 0 - 72 (0 being the blender pencil), but on the open stock pencils we can buy in the UK the numbers aren't linear, instead they have numbers that leap around. To keep track of my Polycolor pencils I've created a printable document with the 72 main pencil numbers and colours on with a space for adding a small example swatch of the pencil colour. If you'd like a copy you can download it here Koh-I-Noor Polycolor Pencil Colour Swatch Chart.

Again there is a discrepancy in that some English speaking art supply websites list different colour names and numbers for the pencils. I've tried doing some translations of the colours listed in Czechoslovakian on the Koh-I-Noor website to no avail, I need to see if some kind soul can give me some literal translations. If in the future I discover that the colour name I've listed is incorrect then I'll update my chart.

All three brands are blend-able with products like Gamsol, Sansador and baby oil, Crafters Companion do their own blending solution that costs around £6 for 75ml. All three brands are light fast. Koh-I-Noor Polycolor pencils are supposed to provide excellent light fastness and water resistance (although YouTube and various internet sources have people saying that they aren't light fast) however the manufacturers website states that the Polycolor Pencils do have "light permanency").

Furthermore on the colour chart on the Koh-I-Noor website each colour has a series of stars, the stars relate to the light permanency of the colour with 1 star having the least amount and 4 stars the most, you can see which pencil is more light fast by clicking on the link.

Another difference between the three brands is that Prismacolor and Colour Blend pencils have round barrels, whilst the barrels of the Polycolor pencils are hexagonal as per my photo above. Which means, for me anyway, the Polycolor are far better because they don't roll away from me when I put them down on the desk, Prismacolor and ColourBlend have a tendency to roll off the desk, hit the floor and break if I'm not  careful 😢

Additionally, both the Prismacolor and Polycolor pencils have a barrel that shows the colour of the lead as true to the colour as the coating can get, but the ColourBlend pencils don't, the white ColourBlend pencil has a tip where the white looks almost pale grey as can be seen in the above photo and isn't an accurate representation of the colour that the pencil lays down.

It was a little difficult to do a proper hue for hue colour test as the sets all contain different colours, so in the end I went for the lightest and darkest pink and green shades from each set to colour the stamped images.

For my test I used 3 different card stocks: -

White = Crafters Companion Neenah Classic Crest Solar White, 216gsm.

Kraft = Tonic Studios Craft Perfect Brown Kraft Card, 280gsm.

Black = Limetree Crafts 'True Black' black card stock which is 300gsm and my go to black card stock for doing almost everything where I want a black base.

For the image I used a clear stamp that came free with issue 191 of Simply Cards & Papercraft, and for each test strip I stamped the images using a Tonic Studios Nuvo Clear Mark Embossing Pad and added some WOW! Super Fine Clear Gloss Embossing Powder, I wanted to focus just on the colour pencils and not highlight the stamp with gold, silver of black edges. Pencil colours/shades used I'm listing here and I'm listing the lightest first, the colours used were as follows: -

Koh-I-Noor Polycolor - Leaves (22 & 25), Flowers (131 & 177).
Prismacolor - Leaves (True Green & Grass Green), Flowers (Pink & Mulberry).
ColourBlend - Leaves (Jade & Pistachio), Flowers (Vivid Pink & Pink Violet).

I also added some squares of the white pencil for each brand to show the opacity. The top white square was blended with gamsol on all three swatches, the 2nd white is just as it comes out of the pencil, and I added a small swatch of the lightest pink of each brand. In Prismacolor's favour, I think the white pencil in their set is a more brilliant white than the others and I think I'd still use that along side my white Polychromos pencil to add highlights to images.

All 3 brands were blended using Gamblin Gamsol and Spectrum Noir Paper Stumps. I laid down a single layer of each colour starting with the darkest first then shading the lighter colour around it before using the paper stump and gamsol to blend the pencil colour smooth.

You can see the results of each colour pencil on the 3 different card stocks above, I want to focus on the results obtained on the black cardstock and specifically the opacity of the pencils. Once the applied gamsol had dried out the pencil with the most vibrant colour was the Polycolor, something I did notice was when I blended the Prismacolor and the ColourBlend with the Gamsol, the colour lifted off and resembled small flakes, the kind you get when you've used a rubber on pencil. There was no flaking with the Polycolor, the colours blended smoothly in to each other.

The Prismacolor did keep more of the light to dark gradation, but they were not as opaque as the Polycolor. The ColourBlend pencils are a lot more translucent than the other two brands, they work better on the lighter coloured cardstock, and personally I don't think that they are a good choice for using on darker cardstock, not unless you are going to add a layer of white first and build up a couple of layers of colour, which is fine if you want to take the time, but not if you want to do some quick colouring.

Polycolor pencils on Kraft cardstock

I've been using the ColourBlend and the Prismacolor for a while off and on, and until now Prismacolor were my go to wax pencils over the ColourBlend due to the opacity of the colour that Prismacolor has. But I'm afraid the Prisma's are going to get a lot less use in the future now that I've discovered Polycolor pencils!

Polycolor's lay down a nice amount of colour without the need for applying heavy pressure and the pencils can be sharpened to a fine point, without crumbling, I found the Polycolor a lot easier to sharpen than the Prismacolor and I think some of that is down to the lead being not as soft as Prismacolor and the wood being better quality, the fact you can get a nice point to the pencil when sharpened makes them really useful for adding details and working on small intricate images.

They also don't leave a wax bloom, at least not that I've seen so far, although the Prismacolor and ColourBlend do if you add a lot of colour. The rose example above was worked on Papermania Kraft cardstock using Gamsol and paper stumps to blend the colours.

The colours blend in to each other really easily and I found them very easy to use, they do leave a little dust (bits of pencil lead) if you apply the colour too heavily, but if you use a light touch they go on like a dream. I found its better to lay down colour, blend it out then add more colour on top if you want more saturation of colour.

They have a nice creamy feel and go on really smooth, the fact that there are less colours to chose from than the two other brands isn't really an issue because the Polycolor pencils blend together so well to help you achieve other shades and hues having less colours isn't really a problem. You can also use a standard eraser (the kind you would use to erase graphite pencil) to remove the colour! The colour doesn't go totally, there is a slight waxy residue left, but you can see the results of 3 shades being laid down a pale grey, dark green and a pink and one pass of a cheap eraser.

Two of the colours listed in the open stock Polycolor colours are Silver and Gold, I don't know if they are metallic or not, when I buy them I will update this post, I've now purchased them, and Polycolor #40 Gold and #39 Silver are indeed metallic pencils and work beautifully. I now intend to add all the Polycolor pencil colours to my stash, for the money they are fabulous quality and I can see me getting a lot of use out of them. Prismacolor definitely have metallic colours but only a silver and gold, and ColourBlend don't currently have any metallic colours, although Crafters Companion do do a set of 12 metallic pencils that can be blended with Gamsol, but they aren't part of the Colour Blend family and they are not as vibrant as Prismacolor or Polycolor.

So in summation and sorry for this mammoth post but I wanted to do a proper comparison, if you want a good quality blendable wax pencil with a good range of colours that give brilliant results then look in to acquiring a set of Polycolor pencils, maybe buy a few open stock colours before you plump for a full set, I think they are excellent value for money and they are now my new go to pencil colouring best friend! And before I go, nobody has paid me to review these pencils, nor have a I received any freebies or incentives to review, the review is based on my personal opinion of products I have bought myself to use in my projects.
