My watermarks are colour poured in shape.
On the canvas undercoated with only liquid white I brush clearly bordered expanses of water.
Highly fluid colour, dabbed with a paint brush on it or brushed, diffuses like by water colour technique and fills the areas completely until the borders with decreasing intensity. Colour reaches that way its highest transparency and luminance. Shapes arise as if they were applied by filmy leaves. My water marks invite to play.
