Question by Mey: Photoshop CS4 my gradient effects only appear in grayscale?
I apply a colored gradient, but it only shows up in hues of grays. What is wrong?

This might sound silly but is your image a black and white/grayscale image? See if the “mode” is set to RGB. If not see if changing it helps. (Image —> Mode –> RGB)
The only two other things I can think of (if the above isn’t the problem) is that 1. the layer you’re applying the gradient to is set to a blend mode causing it to look gray on your image (set it to normal if it’s not and see if it’s still happening), or 2. you have an adjustment layer affecting your gradient layer perhaps — apply a new gradient to the top-most layer with absolutely nothing above it and see if it’s still happening.
