hvs node changing input colors with viewport compositor

The problem of #106965 is that I think the solution get both backwards... like are you even supposed to clamp? I don't think it should clamp values to 0-1 in either cpu or viewport composition...…

hvs node changing input colors with viewport compositor

add a color correction node and boost saturation to the max then add an hsv node. The view port will change.

the viewport comp is on the left and the cpu comp is on the right

HSV in viewport compositor give different result than on CPU.

the hsv node before the hue correct seem to keep my colors for the cpu

  1. colors look the same out of my yuv group (gpu and cpu)
  2. colors change between cpu and gpu with unmodified hsv node…

the fix did not fix the problem for me, all it did was make the color shift happen on the cpu the same as it did on the gpu .

That one was about the hue correct node and this one is about the hsv node, but the issue is related

understood. I just tested it with the color correction node and pushing saturation high, just adding the hue correction node greatly desaturates the image (mostly the yellows). In its current…

You are correct, my mistake from testing. In the test 2 example if you reset the curve you will still see the problem

Think It might be a clamping problem, did a quick test with subtracting the image and was able to replicate it. test attached

made a smaller node setup. You can use the same image from before. Mute the hue correction node and you should see the colors shift, if you replace it with a new hue correct the same problem happens.

If I disable the nodes before the hue correction (in the same green frame), the problem doesn't happen.
