Arrow colour

After I changed my arrows, I experimented with the colour a bit trying to find out if I was going to use two different colours, the same for all arrows or a gradient.

After I tried those options, I decided to stick with the gradient because the fact that it starts of bright and then slowly changes the colour to dark, leads the eye the way it is supposed to go (along the arrow). Because that process keeps repeating from arrow to arrow, the eye follows the circle.
