Aces color problem Sept. 28, 2023, 5:43 a.m.

Thanks for the reply!
I wasnt using the color picker in H, i heard there are some issue with it,
thats why i was using that converter https://ajalt.github.io/colormath/converter/ [ajalt.github.io]
adding there my choosen color ( #b030de) and then looking for values for Aces-cg, and then i copy/paste them into houdini directly to color sop.

But then once its render and comp with ocio the result is different (like the screenshot above) ?

Aces color problem Sept. 26, 2023, 10:58 a.m.

Hello Everyone!
I am using H 19.5.640 with RS 3.5.16
I was using this converter to have specific color in the render https://ajalt.github.io/colormath/converter/ [ajalt.github.io]
but to test I went to https://color.adobe.com/create/color-wheel [color.adobe.com]
I did a screenshot of it, took the middle purple color with #b030de srgb values, used the converter to have that same purple in H.
ACEScg RGB 0.31007, 0.06731, 0.64968.
color from adobe page:


In H made a grid, and color sop, copy the numbers from the converter. Put the render to fusion, added the OCIO and compared to the original color and its not matching ?
Here is the screenshot of fusion viewport, (top is adobe page, bottom is rendered grid (after ocio node) merged with bg color. to show the difference in colors.


Anyone know the solution to fix it ?
(I know there is a chop conversion option used for textures, but here is for specific color values only)
Thanks a lot!
