Hi, pinkflowers! So glad it has worked out for you to participate.
I've been in a quandary over value. My plan as of today is to use my darker gray with units using purple, so as to avoid a blinding contrast (and possibly my darker pinks), and my lighter gray with the lighter colors. The lighter gray isn't really gray, but white with very pale gray print, so it is bright. If this seems to be looking too odd, I'll use the lighter gray for everything.
