The word ‘texture’ is used in two rather different ways when talking about watercolours. The first with reference to the painting itself; the technique used in the painting - so one can talk about ‘experimenting with texture’ or ‘the effects of adding texture’. The second refers to what is being painted, especially to its ‘surface texture’.
I am more interested in the second. Attempting to relay to the viewer, not just the surface texture, but also the material of the object (peeling paintwork, rusty metal, glazed tile); the feel of it (the unpleasant sharpness in the cracked paint) and even the sound of it (the screech and clatter of the garage doors in Angelo). In other words, trying to convey the essence of objects through the medium of watercolours.
