Here is my attempt at the PMS to CMYK color matching, it was pretty tough! The first set of colors are the printed ones, and the second set are the color-aid colors. It seems like the cmyk colors are all a lot more saturated than the ones I'm trying to match them too, so I need to work on toning down the brightness. And of course, there is some color tweaking that needs to be done too.
And these colors are my attempt at an RGB match-up. It's not as easy as I thought it would be, although it was easier than the CMYK version. Using the color chooser, it was nice to be able to change each variable ever-so-slightly. Nudging saturation or value or hue, one little digit at a time. It was also a nice way to see how the hexadecimal color-coding system works.
