Review your instructions and see if they want the blending mode of any the layers changed.
In this tutorial, How to Add a Glitter Effect in Photoshop: 12 Steps,
the instructions call for the blending mode of the color overlay layer to be changed to "color burn".
Consider posting a screen capture of you document showing Photoshop window include you image layers palette and point to whet you having a problem and any dialog you having a problem with. It hard to follow what you wrote without any referent document to look at. A link to the tutorial your using would also be a helpful addition.
I think this has got it. I must have missed the color burn part. I have been working on this forever. My glitter effect does not seem to look as good as the one on the tutorial and so I am going to start over and try it again. I did find one thing that I had a problem with when changing the color, and that was my main background is grey and I needed a white glitter look but when I put in a white color it stayed grey. I didnt seem to have any problems with any other colors.
JJMack- Thanks for that advice I will do that next time I have a problem.
Thanks for reporting back, Cake Master. I'm glad I was able to help. J.J. has the better methodology, I just guessed you missed a blending mode instruction.
