Coloring compound blocks

When you create a compound block, it is colored cyan; however, you can selectively change compound block colors.

Note: If any of the following compound block parameters are activated, a specific diagonal line color overrides the selected custom block color. When multiple parameters are activated, there is an order of precedence for the displayed diagonal color.
