I got one named after me! I feel special :D
Here are some of my suggestions, all based on Latin words that I felt were somehow related to the colour:
White - Lucemite ("light" = "lucem")
Black - Obscuromite ("dark" = "obscuro")
Purple - Arcanite (one of the possible translations of "mystery", being "arcanum")
Blue - Caelirium ("sky" = "caelum")
Green - Viridium ("green" = "viridis". I tried "nature", "grass" and "plant" but they were all too obviously translations)
Yellow - Felicitium ("happiness" = "felicitas". Yellow has historical links with wealth, happiness and freedom)
Orange - Delorite ("amusement" = "delectationis". Orange has historical links with amusement, the unconventional and activities/events)
Red - Perinum (so tempted to just go with "ignite", but I resisted :P It's based on "danger" = "periculum")
If there's anyone here that actually knows Latin, I sincerely apologise for any mis-translations. Blame Google Translate, I just know that the rights words from Latin can look really awesome, so I used Latin as a base for all my words :P
