This time I wanted to do a monochromatic abstract painting with my colorex paints, and as I had opened the bottle with the green hue a short time ago I went for green. I added some yellow for the lighter greens, and some black and blue for the darker ones.
It was fun doing it and I am pleased to see what can be done with a limited palette.
The only sad thing however is that the colorex paints are not lightfast at all. They are not based on pigments but on dye. In this aspect they behave like markers do - and the good thing is that I've got a marker painting which I put framed behind glass and I have it for over three years now and cannot see any change in the colours. Of course I would never sell it.
