Ok...not sure if this will help anyone...since all computer screens are different. But here is the color-in chart that I use for my markers...I haven't updated it yet with my last order, but if it works...I can redo the photo with the rest of them.
The online swatches are HORRIBLY OFF on many colors...and I bought quite a few colors based on recommendations of others thinking they would just be WRONG when I saw the swatch in my shopping cart...but they got here and were perfect! So in person, these colors do look different!
Hopefully if you have a few of the same colors as I do, you can get a good idea of what you want next...and what you don't!
This chart was printed on PTI CS...on geogia pacific CS the colors looked a bit more grayed-out.
A nice thing to know is: You don't need all 322 Sketch colors EVER. Many are nearly identical to each other. Check out the library at copicmarker.com and click on color wheel to see which ones. (This chart is there too) I printed that wheel and checked off what I have, so that when I order more, I don't buy one right next to one I already have, as the one I have can be used instead.
Hope this helps!
No longer stamping...on to bigger things.
