Note checks are dumb.

In Starbound you have an option to change your human character's underwear color, but you have no idea of checking what color it presently is. It turns out that a Floran's leaf color corresponds with undy color. Check below:

Floran Green - Human Black
Floran Brown - Human White
Floran Yellow - Human Grey
Floran Purple - Human Pink
Floran Pale Green - Human Blue
Floran Pale Yellow - Human Purple
Floran Pale Blue - Human Red
Floran Orange - Human Orange
Floran Red - Human Yellow
Floran Pink - Human Green

You've no excuse now.
