Thoughts on Colour Mixing, Green Blue Grey

 

Continuing with the thoughts on colour mixing, here is a demonstration of the green gamut that I have been using lately. A gamut describes all of the possible colours you can make with a given number of paints. Here you see yellow (PY154), yellow-orange (PY110), green (PG36), and dark green (PBk31) mixed in a belt shape. Inside are examples of the range of greens that can be made, including chartreuse, sap green, forest green, olive green, and dark yellows that look green. I selected the orange paint- isoindo yellow (PY110) - after trying out quite a few. This one makes nice bright olive greens. These colour mixes are handy for making all manner of grass, trees and foliage. By adding more yellow and yellow-orange you can simulate the the effect of sunlight.

Another important range of mixtures for landscape are the blue, grey and neutral browns. These can be used for tree trunks, rocks, concrete, sky effects, shadows, etc. I run most of the mixtures off indo blue (PB60) with burnt sienna (PR101) or raw sienna (PBr7). By adding vivid blue like phthalo (PB15) or cobalt (PB28) at can become a flat cool blue, like a worn pair of jeans. Hopefully the weather is okay tomorrow, I have been holding off of outdoor painting until it warms up a bit!
