One of the abilities of my user-defined command is to take a specified graphic area and convert its color in the opposite direction (White blance instead of black). For instance, if you used SPCOLOR, you could change its color, but it would get darker as a result. With my command, it can go in the opposite way, and get lighter.
Is there already a command that does this? I feel like there is...
