hey, I am using the Color Correction image effect in unity. I use Gimp for the Ramp, when i apply the custom ramp some pixels in some of the mesh turns red/other colors.
Here is the Color Ramp:

Here is an example:
Did you intend to change each of the RGB channels equally? The ramp you have posted is not actually pure greyscale, the green is about ten levels higher than red and blue.
im still new to this color ramp thing, so you can’t change the RGB values at all? just the black and white?
The RGB channels of the colour ramp affect the RGB channels of the texture independently. You can set them to anything you like but if the ramp isn’t a pure greyscale image then the texture colours will be affected as well as the brightness.
okay on revisiting this problem, I set it to gray scale and it still messes up the colors
be sure that your ramp texture is set to Point filtering, Clamp and Truecolor, I had the same issue and changing those fixes it. The issue is by default textures are bilinear and repeat, so the edges were being blended and messing up the ramping.
Yeah, the most common mistake is to leave the ramp texture to a Repeat mode.
Doh thanks for that !
