Here are some of my ideas using my favourite colours to depict my favourite themes using the computer package called Paint. It is great fun to create images quickly and it means an artist could try out an idea and colour schemes without having to find the exact pigmentation in an oil paint.  I remember my tutor advising me that the red I needed to paint skin tones well, was called crimson not rose red. So if you get mixed up with your prussian blues and rose reds  This form of art means one can indulge their ideas and mix colours online without having to leave the office to buy paint!
