Draks on Planet Icarus come in 12 colors, where each color name is a combination of a body and wing color. These can be the same or different (See chart 1 below). The colors are approximately equal in distribution, and no one color is more important, special, or rare than any other. All the colors have certain personality traits and physical characteristics that are as ingrained in their genes as their colors. 
In recent years it's become known that regional differences do exist and that sometimes drak colors aren't as fixed as was once believed. Sometimes a day might be white with yellow or white with orange, even white with pink is prevalent in some areas (See chart 2 below for options). 

As with all species, genetic mutations can occur, although mutated Draklings that survive to adulthood are very rare. Mutations in hatchlings often prevent the egg from surviving or hatching. But on occasion, the mutated eggs can hatch, often producing strangely colored Draklings. These mutations are very rare and occur, on average, in one in every 100 Draklings (note: working number is 5 in 100 as the lower number just doesn't work).

Practical Information: You can name these colors differently (most Icarian colors have a natural theme), but please list the "official" color somewhere, either in the name or behind it between parenthesis so it won't be classed as a rare. The names listed below are records from prior "strange colorations" and suggestions by the active castles.
