This is an interactive colorpack for Gallery. It has the colour groups, named ColA etc, for people to insert their chosen colour scheme into the basic css file. Instructions are in the txt file which is given here for previewing, and also included in the zip file that you can download all at once.
THE CSS FILES HERE create the color schemes as shown in the corresponding screenshots. Replace the css file in the basic Uselect colorpack with whichever of these you desire.
The idea of the Uselect Colorpack is to make it easier for people to create their own colour schemes.
