This is my personal Copic Marker Color Chart.
I own the Copic Sketch and Ciao but not all the available 334 colors (I own 229)
I marked the colors I use most and like a lot with a pink heart because it was requested a few times - so this is my answer ^^ but I think I like a lot more colors than just these.. it was hard to decide
If you want to buy markers don't buy any of these set - I think they don't fit together well. Start with Copic Ciao they are cheaper and available in 144 colors. The first letters show you the color family. The first number stands for the saturation and the second for how light the marker is within that saturation group.
Please keep in mind that the colors on the monitor look a bit different from the original ones (depending on your settings) and can look on other papers different too. I used "Schoellershammer Markerpaper"
Hope this will help you ^^
