Hello JoshieZombie,
You could try checking sRGB to true inside of your texture editor.
Changing to an 8-bit image is the tried and most effective method for fixing this issue.
If you are looking for a quick work around, there is also the option :
1.Create constant vector
2.Add multiply Node
3.Add your Texture sample into the A of your multiply node
4.Add your constant vector to your multiply node
5.Plug that into your Base/Diffuse Channel
For more control after the multiply node add a clamp node and set the min to 0 and max to 1 ( This will set a value that cannot be exceeded for any values higher than 1.
Thanks,
