Documenting Colours

Don't u just hate it when u want to rework a painting and u cant remember what colours u used? Aaaargghhhh drives me nuts! From now on I'll be documenting every painting and the colours I used. Yes a colour chart works too! I highly recommend doing Richard schmid's colour charts. I find them very useful, saves me a ton of time. When designing a painting, I simply use my colour charts to map out my painting and the colours I'll be using. If I'm not sure of a colour, it'll be on my colour chart for sure. How simple is that!
