Sometimes when I see a livid red or fuchsia against the right green or teal, my mouth waters a little bit, my eyeballs buzz. Little explosions go off inside my head. The colours make love, deliciously shocking, lying one alongside the other.

I don’t know why it is that colour brings me such joy.

Why should the simple act of seeing, keeping your eyes on something long enough to really drink it in, deeply, bring so much pleasure?

Thankfully, it does.
