Rainbow Eucalyptus trees on Maui, Hawaii
These haven’t been painted. The phenomenon is caused by patches of bark peeling off at various times and the colors are indicators of age. A newly shed outer bark reveals bright greens which darken over time into blues and purples and then orange and red tones.
I looove these trees.
This is part of why I hate the phrase “That color is not found in nature!”
If you haven’t found a particular color in nature, you’re not looking hard enough.
