Retopo - How do you select cluster of different coloured regions?

[DustyShinigami]

Hi. How exactly can you select a specific coloured cluster of faces? What I mean is, I've added UV seams, so areas are separated into different colours - green for the front faces of the mesh, purple for edges on top, bottom, and the sides, and yellow for the inside faces - and I want to select just the front and edge regions so I can delete them. But using the Select tool, double clicking on any coloured region just selects everything. I've tried Unwrapping it all to see if I can select the Shells in the UV Preview window, but I'm not having any luck with that either.

Thanks

@DustyShinigamiYou can do this in the UV preview window. Click on the UV island and delete it.

Awesome. Thank you. Although, I could have sworn when I tried selecting things in the UV Preview window, it wouldn't select anything. Or just everything instead of individual shells. But that's sorted it.
