i remember reading a technique for adjusting face tones by somehow aligning the red blue and green colors in a 45 degree angle but don’t remember the details. anyone have some info on this?
A good, average skin tone for any racial group should have significantly more red than green, and less blue than either red or green. It is centered around a hue angle of about 20 degrees, from about 0 degrees (for very pink skin) to about 30 degrees. The easiest way to check this is to set the info palette to HSB mode, and set the hue to about 20 degrees.
A hue angle of 45 degrees is at about the upper limit of yellow for any skin tone. Saturation is less important than hue, but also affects the appearance- too saturated and the skin tones will look painted on or radioactive – too little and people look drab and sick. Brightness can vary greatly.
"Pinning" skin tones by controlling hue and saturation is an important part of the curvemeister plugin.
