(OK, this is the real picture that NASA posted today. The explanation is interesting, but scroll down to the photo and you will see what I mean. I will post some other photos below so the thread will have a real photo in it!)
Explanation: What color is the universe? More precisely, if the entire sky were smeared out, what color would the final mix be? This whimsical question came up when trying to determine what stars are commonplace in nearby galaxies. The answer, depicted above, is a conditionally perceived shade of beige. In computer parlance: #FFF8E7. To determine this, astronomers computationally averaged the light emitted by one of the larger samples of galaxies analyzed: the 200,000 galaxies of the 2dF survey. The resulting cosmic spectrum has some emission in all parts of the electromagnetic spectrum, but a single perceived composite color. This color has become much less blue over the past 10 billion years, indicating that redder stars are becoming more prevalent. In a contest to better name the color, notable entries included skyvory, univeige, and the winner: cosmic latte.

Black color....
Also the color of my mood if a certain dementia victim is inaugurated in 2021. We’re talking depressed.

Beige...or maybe off white!
The universe is the color of suburbia!

Just think, there could be a hamburger joint out there that only served cheeseburgers. Or there could be many.

Start some bright bill boards on the Moon, that can be seen from Earth, then beautify the asteroids.
