This may not be the proper place for this post, but I think it is more fitting here than stackoverflow.
I am attempting to implement the triangle inequality average fractal coloring algorithm based off the following paper: http://jussiharkonen.com/files/on_fractal_coloring_techniques%28lo-res%29.pdf
I have a working julia set being displayed but haven't been able to get the TIA coloring to work. While the julia set is iterating toward the max itr/escape size, an average angle is calculated. That average angle is used to color the graph. I have followed along closely to the paper but my results are nothing like what is show.
I am not really sure where I could be going wrong.
My example: https://www.shadertoy.com/view/Md3fDs

I believe my algorithm is calculating the angle correctly, but I am not sure why my colorings are looking the way they do.
