What colour are grass and trees?

Green is yellow and blue mixed together. Moving the sliders on each of those will give you varying degrees of green.

:lol: HTH ;)

Edit: A bit more to help you understand (Something I actually remember from GCSE Art :woot: school wasn't a waste after all!)

Red, Yellow and Blue are primary colours. Mixing two of those give you secondary colours which are: Red & Blue= Purple, Red & Yellow = Orange, Blue & yellow = Green. Some more info on Secondary colours HERE.

Black and White are shades, not colours.

Ta da! :clap: :lol:
 
Lazyness :shrug: Saves you moving two sliders, and because green is a colour used a hell of a lot in photography I guess it's just easier. No real answer for that though, just a guess.
 
theres additive colours and subtractive primary colours

subtractive colours are used to print on white paper etc , these are magenta (red) yellow and (cyan)blue

when colour is displayed on a monitor its additive colour and they use red , green and blue

hope this makes sense
 
I dont think primary colours and the theory of, really come into it.
Grass is a lot more yellow in colour than green.

The theories above would indicate that changing the blue slider would effect the colour of the grass too. Which is not the case.
Your also dealing with RGB, so green is a light in its own right.
yellow is actually the combination of red and green in RGB, which is very different from saying green is the combination of blue and yellow.
