How do i change a color in this style?
Use Firefox, goto your board-startpage, push F12 on keyboard. Use the "picker" down on the left and pick up a colored item. Find the color on the right and change it to the color you like. Copy the color-code to your colors.css-file and go on with the next item till you like the result.
If you think a color is totally wrong, please tell me, so i could fix it.
