Muting the colors of a color table


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?
