Here is an example of a unusual minimal painting, striking minimalism is the closest description, it is a painting with intensity and contrasting black lines. Watercolour is used to create the subtle changes in intensity and black lines to create contrast.
Simple? maybe, as there are only three identifiable shapes. Easy? No, the subtle intensity changes are a challenge and watercolour does it the best.
A minimalist painting with a geometric design painted in watercolour so that the intense colour variations can be magnified. Striking minimalism for sure!
