Thanks for all the inputs, I think I now understand what this color is. It's not a color I 've ever liked with my skin tone, but I could see trying it as a little bit in a pattern or otherwise away from my face.
FYI tanstaafi I found the definition of chartreuse by doing a simple google search, and some of the definitions say it was named after the liquor by the same name that happens to be that color. A circular definition...not much help there!
Viva I like the idea of "sister" colors...or maybe fraternal twin colors
Thanks Angie!
It's funny how terminology for colors changes over time...what we now call "neon" was called "dayglow" when I was a teenager. In another generation there will probably be another new term.
