So I found a couple of bugs in the saved settings that have been squashed and also found some settings were REALLY annoying being saved so I have disabled a few of the saved settings.

Onto the main brunt of this update. I have added a new tab "Colors" in this tab you can cycle through the shape, ground, and ceiling  and alter the colors. Here is the simple grey brick texture...

As you can see you can now change the colors of the shape before you output your image set(you can see the original color in the right hand texture window)

This has not been added to the help menu yet(I will try to get around to that soon, theres just always so much to do)
