Title: No "green" in photographs
Post by: Slurm on May 11, 2013, 08:26:11 am
This is my first post on the luminous landscape forum  ;D

Why do digital photographs contain so little information in the colour range defined as "green" - I find even images of what appears to be bright green foliage have a very small number of pixels that respond to selective colour / hue / saturation adjustments targeting "green", and these apparently vivid green hues are actually within the "yellow" range, as defined by photoshop? Just wondered why this is?

In a nutshell, language is not very well color managed.  If we painted well lighted foliage with true primary green, it would look way to cool to most people, or like it was in deep shadows.  Another interesting case is the way the Japanese relate blue and green in language use.  But there's a lot of yellow out there in the world, and that's the color that goes fastest on my Canon printer.  Watch the RGB values as you run the Arrow across those "green" leaves.
