I'm going to throw my opinion out there, for what it's worth.
I feel that Zalanthan colors and descriptions take precedence over earth colors, and though Zalanthan colors are preferred, both are acceptable. When I see the honey-haired woman, I'm thinking green hair, not only because I've spent so long playing this game that when I see honey written in grey text on black background, my first thought is 'green', but also because I (perhaps unfairly) expect the other player to mean green. However, we're not all Zalanthan lore experts, or masterful writers with prolific vocabularies, so atramentous may not even be a word that we're aware is a color. If you can't think of a better way to describe golden-yellow hair other than honey, so be it. I'm not going to be upset, but until I look at your mdesc, I may be confused for a moment.
This only stands for and works well with text that IS NOT speech. Once it becomes speech, it, in my humble and loudly repeated opinion, MUST be IC and Zalanthan. As pointed out above, we don't say "'sup dawg" "Sir or Ma'am" or "That's cool." So we also shouldn't say, verbally, 'Sky-blue eyes' or 'Honey-toned skin' etc because it's not reasonable for our chars to do so, but also because our veteran players like me are old and fragile, and my forehead can only be banged upon the desk so often before I lose my ability fragment sentence groups.
tl:dr Both are okay, but it's suggested to learn Armageddon colors.
BTW, Bardlyone may be able to hook you up with Arm Mushclient triggers that turn words that describe color into colorized words. 'Honey' actually shows up as green, cunyati as brown, and soldier and Templar are highlighted red in my list of triggers. It's pretty useful, and it meshes well with the new color palettes offered by staff. Send her 172 PM's daily for a period of eight days to receive these triggers.
