When you hover the cursor over an item in your inventory or hotbar a screen pops up to give you information about that item. My question is what do the colour fonts on the item's name mean?
For example:

Why is Fly in Amber in a purple font?
I think they are to do with things like whether it's decompilable, whether it loses stability etc but which colour goes with what?
Other colours I've seen are grey, white, green, yellow, orange and red.
