Good post Tim, I followed!

I have a couple of technical comments/additions since this is very close to my field of research!

Most objects reflect light but before that happens they adsorb part of the light they receive. The wavelength they adsorb determines what your eye will process later. For instance when all wavelengths expect red (780nm) are adsorbed the object will reflect red. Same goes for a blue steemit logo for instance. The logo absorbs all wavelengths expect the blue.

There's one thing missing here. This doesn't cover the case where light is emitted by the object!

It becomes important when describing the Steemit logo, which is displayed on computer monitors most of the time. If you have an LCD monitor, then the logo does absorb everything but blue (since it uses white light and blue filters). In the case of OLED displays, however, each pixel emits light with a specific, narrow band. Hence, the Steemit logo appears blue because it emits blue!

Additional technical nitpicking: the color you see is also dependent on the illuminating light. So if you shine blue light at something that absorbs blue light, it'll be black, no matter what its absorption is in the green or red.

How does reflection and adsorption work?
To understand how adsorption works we need to have a closer look into the chemistry of molecules.

That's true when looking at pigments, but there's also such a thing as structural colors, which functions in a completely different way!

Edit: I believe you meant to say absorption and not adsorption, they look and sound similar but aren't exactly the same thing.
