if black is all colors and white is no colors what is gray?

An important note first; this only applies to digital color, as in the real world shadows just inherit the color of the surface they’re on, and in inks, you can’t create black and white, they have to be their own separate channels.
But with digital color, it works. Color is created with light using three channels: red, green, and blue. With brightness values that range from 0-255 (this is more of a technical limitation, but it still works.) When you want a pixel to make a certain color, you just adjust the brightness values of each of those three colors. Fun fact, unless you’re creating red, green, blue, or white, the maximum brightness of any true color is only 50%, as going any higher would desaturate it.
Anyway; so the way you create shades of grey is by setting each color to the same brightness value, as that will make them evenly mix and create white, but darker if it’s not all the way at 255.
