After creating a black (or white) vignette using the guided edit in Photoshop Elements 14, can I then change it to a specific alternative colour? If so, please tell me how. I am a beginner to the programme.
If you create a layer, you can then apply the vignette to a mask. The mask could be used to apply color at varying degrees of transparency and with any color that you apply using a paint bucket.
Yes using some frequency tricks , you can change the color. But as you are now beginner. That would be a new thing for you..
Check some tutorials on frequency separations and more. I saw a tutorial on the same long time ago.
