  1. I am working on a project within PIXI that requires me to shift the hue of a saturated rainbow gradient in a loop so it looks like its moving. I figured this would be cut and dry, since changing the hue of said image in Photoshop make it appear as if its moving. When starting out and getting the filter in place and animating, I was perplexed by the results. The colors looked nothing like I expected nor could have predicted. You can see a little demo of what I'm talking about and seeing on codepen here. I started digging to see what could be the problem, trying different image formats and color depths to no avail. I gave a shot at another canvas solution, GLFX, and can get the proper results I expected, as also seen on codepen here. My question to you guys is whats going on here? I am suspecting either an error in PIXI or my understanding of how hue rotation should work. I tried a few different PIXI revisions and didn't spot a difference. I dug a little further and came across an article explaining the difference between HSL and CSS hue rotations and its inaccuracies here. Though, that doesn't help me fix the issue with PIXI. Anyway to fix this on my end while staying within PIXI? Thank you.
