The new arrows are the same color

So when I downloaded 15w31c
I looked at the arrows and all of the new arrows that were added and the arrows color weree the same except their names.

(Excluding the regular arrow and the spectral arrow)
Steps to do it
1. Be in 15w31c
2. Load world and be in creative mode
3. Look for the new for the new arrows
I have no screenshot of it.
