Is there an easy way of setting a transparent color that will not be displayed in bitmap textures? I'm starting a simple 2d rpg and would like to avoid using seperate masking textures, is this possible? If it is not, then does anyone know an easy way of creating a mask for a bitmap? I'm using openGL and c++ Thanks for your help!

Is there a problem with using 32 bit colour? This is what the alpha channel is for.

Check out NeHe Lesson 32, which covers alpha testing (as well as sorting/picking). Good luck!
