I am a relatively inexperienced and totally self-taught (meaning there are probably glaring knowledge-lapses) Photoshop CS3 user.
I want to have my text show up in a different color, depending on whether it is over the background or an ellipse.
Basically, the background layer is a light blue color. A separate layer has an ellipse which is a dark blue. A third layer has text that starts to the left of the ellipse, goes through it and extends to the right. Where the text is not over the ellipse, I want the text to be dark blue, when it is over the ellipse, I want it to be light blue.
I am sure there is a really easy solution to this that I am not seeing.
use two type layers, set with the two colors you want. Set one above and one below the ellipse layer. Clip the top one to the ellipse below by option clicking between the type layer and the ellipse layer in the Layers palette.
