Hi- We have various displays where we map data to RGB or RGBA. One of the users asked if we could tone down the saturation of a particular background topography image so that data overlain on top stands out more. Not knowing anything about color, I tried adding in a ConstantMap of .5 to Saturation, but that had no effect. I though of using transparency, but that is going to be order dependent so isn't really a solution. For a given color pallete, what's the best way to "mute" or "tone down" the colors? Thanks.
