HueCorrect
Curves over hue (red, yellow, green, cyan, blue, magenta) that change saturation, luminance and red / green / blue gain, and suppress a channel (r_sup / g_sup / b_sup) for the hues you choose, e.g.
Curves over hue (red, yellow, green, cyan, blue, magenta) that change saturation, luminance and red / green / blue gain, and suppress a channel (r_sup / g_sup / b_sup) for the hues you choose, e.g. to take spill out of one hue range only. A grey pixel has no hue, so it reads the curves at the red end only.
