Linear vs Gamma color space for ui font rendering

[bgolus]

Yes-ish, if you know you have white text on a black background or vice versa:

Fade to Black in Linear color space

So, here’s an example of the above working. There are 4 bars below, each is using the i.uv.y to interpolate from one color to another. The first bar is what you get with just lerping the two colors values with i.uv.y. This is what you’re trying to avoid. The second bar is converting the colors into gamma space, doing the lerp with i.uv.y, and converting back into linear space, which properly recreates the curve you see when using gamma color space rendering. i.e.: This is what you’re trying t…

One other option would be to use a grab pass shader. This will likely be noticeably more expensive than other options, but would let you blend the grabpass color value in sRGB space.
