- A Paintbrush (preferably - for your own sake, not a very expensive one.)
- A cup of water
- Red, yellow, blue and white acrylic paint
- Something to mix the paint on (plate, palette etc.)
Know your basics.
- red + yellow = orange
- yellow + blue = green
- blue + red = purple
When two primary colours are mixed, they create a secondary colour.
Advancing on that.
- To kill purple - you add yellow.
- To kill green - you add red.
- To kill orange - you add blue.
It's simple really, if the colour is light, add white. The more you add, the lighter it becomes.
To that colour add the killing colour - in this case blue.
Is the colour looking slightly green? Add red.
Is the colour looking a bit orange? Add blue.
Is colour looking a tinge purple? Add yellow.
Now, to put it into practice.
- Get a sheet of paper - less than a quarter of an A4 piece of paper.
- Make a tiny hole in the centre of the paper.
- Get a picture of some sort and cover it with the paper so that there is a particular colour in the hole.
- Keep the paper in place with blutack or sellotape.
- Try and get that colour using your newly acquired knowledge! Mix it on a plate but when you think it's close, test it on the paper near the hole.
