bk — black bl — blue br — brown cr — cream gn — green gy — gray mg — magenta or — orange pp — purple pk — pink rd — red tl — teal tn — tan wh — white yl — yellow
tt — two toned for body, fur and hair mc — multicolored for body, fur and hair
Things that have that color:
bd — body bg — background fr — fur ft — feathers sc — scales
So for example instead of writing "yellow feathers" you can write "ylft" or instead of "orange fur" you can write "orfr" and because those tags are aliased they will be changed into the proper tag. Example: blsc I hope this will save us all time :)
If somebody finds it useful I can make them for eye colors too. Just tell me which two letters should stand for "eyes".
EDIT: I did tags for eyes, I hope nothing is missing.
