From colour to white and back to colour again.
I started with a 12″ x12″ stretched canvas and brushed on a green background with acrylic colours.
I made rows of triangles with orange tinted crackle using masking tape to form the shapes.I gessoed over the surface, then sanded them back to show some of the colour. Then I added more blocks of tinted crackle
I applied another layer of gesso and sanded back again.
Then I added watercolour washes on top.
Some closeups showing details.
The canvas is like a little library of crackle colour combinations.
