Geology: “I always get my colors from nature,” says Toogood. (Her signature blue occurs naturally in the copper mineral azurite, shown here). “I’m very into grass, natural materials, rocks, things I find in the ground — it probably comes from growing up in the countryside. I wish I could dedicate more time to studying the unexpected colors and compositions found in minerals and rocks. Why didn't we get geology lessons at school?”
