When I was in primary school, I used to look at the drawings of some of the other (artistically-talented) kids and think how beautiful their trees looked with splashes of different greens and yellows mixed in. My trees were always the one flat shade of green, and even though I soon learned to mix it up a little – lighter on top and darker at the bottom, for example – it would be a few more years before I realised those kids weren’t adding colours to make their trees more beautiful – even though they were – it was because real leaves on trees are made up of different shades of greens and yellows.
