Cosmic Latte


About 20 years ago, when my sister was still about 10 years old, she asked me “Why do clothes look dark when wet? Water is colorless though.” I’m sure she asked idly without thinking so much, but the question flustered me a lot. Now I know it was exactly the arrogance and ignorance of youth (or only me younger days). I was arrogantly surprised at that time to find that there are still things that I don’t know, even among daily little events. By the way, are you interested in the answer to the question? It’s because water is low in optical reflectance. It’s about half as much as that of glass, which may contrast with the impression you get from the sparkling surface of the seas and rivers, though.

Speaking of colors, what color do you think the universe is? Black? Colorless and transparent? As many of you may have already known because the discovery made the news about 20 years ago, it is said to be beige. To be more precise, it’s the average color of the universe. New and hot stars look blue; old and cold stars red. If the colors of those stars are mixed and equalized, the color of the universe will look beige. The color was later named “Cosmic latte.” You can see how it looks by googling with the color name.

The other day, I talked with the interior coordinator of our shop. I asked if there’s any rule to decide the wall and ceiling color of our shop. She answered “it’s basically a color between gray and beige. It’s a color called “greige” that seems to be popular in the interior design field. She added it wouldn’t interfere with the colors of wood used for our furniture. On hearing her explanation, I remembered the above trivial stories and idly thought to myself “Let’s call the interior color of our shop grayish cosmic latte, rather than greige.”
