One of my earliest memories is telling the Gingerbread Daddy that I didn't like purple and yellow together. I didn't think they ... matched. My father explained how the colour wheel worked and how colours complement each other. I still wasn't entirely convinced. Then he told me that if the colour combination works in nature, then ... well, then it works. And nature seems particularly fond of the purple/yellow combo, so who am I to disagree?
It seems that Mother Nature has a pretty whacky sense of colour, though, and a lot of my crochet work reflect the type of colour combinations that you see in the hothouses of a botanic garden. But I've gone back to my roots (cue corny Irish picture):
This is the Wicklow blanket, because the greens and browns and blues remind me of the landscape, the purples remind me of the heather that grows in the stoney Wicklow Mountains (well, they'd be hills by Alpine standards, but they're still big enough.)
