Color-changing green sandalwood
Share
Green sandalwood is also used as an aromatic wood, and when you put your nose close to it, it actually smells like fragrant grass.
And the most distinctive feature is that it changes color when exposed to sunlight, or more precisely, ultraviolet light. Before exposure to UV light, it is a bright reddish brown, but after about 30 minutes of exposure, the color gradually changes to a deep green.
The left side of the photo is the original color, and the right side is the green sandalwood after 30 minutes.
Wooden watches allow you to enjoy color changes like this.
