African Marigolds

The camera has recorded green as green. But to our eyes when we were there in the garden at Anglesey Abbey, the leaves were blue.

But they only looked blue when looking at them from a certain direction, with sunlight raking at a certain angle. And if we cupped a leaf in a hand, it looked green.

We were so intrigued that we asked a couple how they saw the leaves, and they agreed – blue.

    1. Yes, as far as I can say, they looked the same to our eyes as they do in the photograph. When we were there in the garden I thought about polar bears. Here’s comment about polar bears from the WWF “Beneath all that thick fur, polar bears have jet black skin. The polar bear’s fur is also translucent, and only appears white because it reflects visible light.” So perhaps there is some element of that in the leaves – green from chlorophyll but also affected by reflected sunlight.
