You should know which way your colours go because if you mix them you could get grey unexpectedly. If this doesn't make sense buy the book.
Paint what you see. She had a problem with egg yolks because everyone knows they are yellow, but really they are not the bright yellow out of the tube.. I had a similar problem with candles (cheesy plug for my other blog 5minutesfromcool.blogspot.ca ) and the colours of flames.
She warned about using white because it makes things chalky - that is what my evil teacher Suzy always says- maybe I should listen to her more. She talked about burnt umber - it sounded so good I may go buy a tube.
The next exercise was to do colour charts and maybe one day I will do them but not today. My inner child is having a tantrum and my outer child says she can`t make me.
She did suggest using paint chips. The exercise is to mix a colour to match the paint chip. This isn't the first time I have done this but a good exercise is always worth repeating.
I think I am pretty good at this and if the painting career doesn't work out I can always get a job putting drops of paint on a paint chip. You can`t even tell the beige ones I did - I am that good.
The orange one does show but if you squint it goes away. Squint really hard.
The colour card is from Farrow & Ball. I keep their card because the names of the colours amuse me. I would love to paint a room Wimborne white or cat`s paw but the winner is elephant`s breath. Say no more, say no more. (from monty python it seemed appropriate).
