I found that using some (0.05) saturation is the reason

I am having trouble understanding this thread. What does "b/n" stand for? Can you explain what was the issue and solution to it?

Hi, Maru,

I had a different color between corona vfb and saved images and when I clone it to 3dsmax buffer in the bright area near the floor ies light. This was caused from the saturation set to 0,05. When I put it to 0 there was no difference. B/n - I mean between

We have a similar issue logged in our tracker. Hopefully the fix will come soon.
If I understand it correctly, this happens because Corona uses Wide RGB color space internally, and this is clamped to sRGB. In the Corona VFB the colors are displayed "as expected", but if you copy the image to Max VFB or save it, it will be probably displayed a bit different, especially if there are things like colors with negative values or very high saturation.
