Is there a way to color your UVs

Hey guys I was wondering is there a way to color your UVs before you export them?

Like after I unwrap the mesh I would like to be able to mark different seams with different colors before I export them.

Is this possible? :confused:

Thank for your help.

You can do the same in Texture Paint Mode. Please check blendercookie.com for a tutorial.

Texture paint mode is awesome. Also, you can paint the image in the image editor as well. Press T with you mouse hovering over the image to get to the paint tools.
