Not a big deal, but would certainly be nice.

Recolour tails with fluff on the end, quite like head items that include hair, would benefit from drawing their "fur" colour from the avatar's hair colour, at least in my opinion. New recolour tails created this way would be able to have three colours instead of two, allowing jewelry, flames, etc. to have their own colour. Here is an example with an old tail.

Pre-coloured tail:


Recolour tail:


GIMPed recolour tail (red as hair colour, black and gold as tail colours):


Possible drawback: Players might want their tails coloured different than their hair.

Thoughts?

I personally like it. I'd use that exampled tail more if I could change the color of the bobbles separately from the fur xD
