Spring in England is so pretty. I have never known anyone who is not stunned by the colour of the grass, the leaves popping from the trees. Yet many of us battle to mix greens when we are painting.
Try this exercise and do it in such a way that you can keep it somewhere for future reference.
Cerulean Blue and Raw Sienna will give a dull green
Ultra Marine Blue and Lemon Yellow will give a mid colour green
Ultra Marine Blue and Raw Sienna gives a dull green good for distance
Cerulean Blue and Lemon Yellow results in a very bright green
What have we learnt-
A bright colour plus a bright colour = a bright colour
A dull and a dull colour = a very dull colour
A mix of a bright and a dull colour = a mid colour
