Experiments with Colour

I have recently discovered that, although I talk about it quite frequently, I don't have very much of my own work on my blog! I have been producing a lot of sketchbook work recently for my current brief, in which I am creating lots of experiments with colour using ink, paint and paper. I think the explosions of colour I have created help to describe the feeling of being free and express the experience of psychedelia. I would like to use these experiments as backgrounds on which I could layer some symmetrical / geometric patterns over the top on photoshop.
