Since I started painting I've really been working on developing my use of colour, my colour mixing until now has been based on instinct and hasn't always helped me get the results I wanted. Flesh tones in particular weren't always matching what I could see. I think I just assumed there was a formula to follow and that a bit of this and a bit of that makes skin colour. Of course that's rubbish. It's all about observation and comparing the colour you've made with what you see and continually mixing until it is spot on.
To build on my understanding of colour and to help me find my colour palette I spent some time reading and practising exercises on colour theory...it has really helped!!!
