I have come up with Copic color matches for the 2017-19 Stampin' Up In Colors!! I have two charts on my sidebar - one is just the In Colors. One is a full chart including current colors, in colors, and all retired colors. Just click on it then print or download.
If you are planning on coloring in the little squares - be sure you print it onto the same paper that you would use for cardmaking. Paper can make a difference in how the color comes up. (My matches were determined using Neenah Classic Crest Solar White.)
The last two years of in colors have been tough to match. Take Tranquil Tide for instance. Hold your cardstock next to Lemon Lime Twist. Do you see how blue Tranquil Tide looks? Then hold it next to Berry Burst. Now the green comes out. So there are multiple matches for many of the colors so you can go in the direction that best works for your card.
One other little hint - if I'm doing any shading with a darker color - I tend to use one shade down from the color in the chart and then shade with the chart color. So if I'm using Berry Burst and the chart says RV66 - I'll start with RV63 and shade with RV66. The more you go over a color, the darker it gets - and since these charts were intended for colors that matched - they might get too dark if you are blending and saturating the paper.
BTW - my Copic collection has grown extensively since the above picture was taken. The purples even have their own bucket now because the other colors took over my storage system!! There are just a handful that I don't own - but none of them were in the range of this year's colors, so I don't think I'm missing anything.
