When we look at a computer monitor, the colors are usually created there by additively mixing red, green and blue.
In the so-called RGB color space, there is a color depth of 8 bits per color channel, so that 256 gradations of the respective color are possible.
Since there are three color channels, the formula 256³ means that each pixel in an RGB image can have exactly 16,777,216 different color states.
Quite apart from mathematics, a question arises: What should one call all these colors?
The collaborative project "Colornames" at https://colornames.org/ is attempting such a Herculean task.
The online community is asked to use a random number generator to display an RGB color that has not yet been "named" (click on "Get Lucky" at the top right) and to give that color a name that is as appropriate as possible.
If your suggestion isn't immoral or intentionally misleading, you're the godfather of this shade, so to speak, from now on.
Of course, you can also use the website passively.
Under the heading "Latest" you will find the latest suggestions from other users - with such poetic names as "Dark Midnight Lavender", "Coffee Stained Table" or "Untamed Sea Wave".
What would you think of with an ashy, somber shade of green?
The current status of the undertaking is also always displayed in the upper horizontal navigation.
At the time of writing this column, exactly 3,212,506 of the more than 16 million possible shades had been named.
So there is plenty to do!
Now our question:
