Arrow color and background gradient

[Glaurock]

When using a background drawable with a color gradient, the arrow color won't adapt to the gradient depending on its position.

I want to achieve something like this (the arrow blue is adapted to the gradient color):

Do you have a solution for applying the right color to the arrow ?
Thank you and good job for that awesome lib
