Art, color: the first recorded color wheel?

Self-tutoring about color theory: the tutor mentions perhaps the first color wheel.

Apparently, Isaac Newton devised a color wheel in 1666 – perhaps the first ever. It was based on red, green, and blue, from which he decided all colors of light could be derived.

Art, color: another side of beige

Self-tutoring about color: the tutor looks more closely at beige and a related color.

The web version of beige is rgb(245,245,220)


Beige background

What if a similar formula is followed, but using less red while almost full green and blue?

Art, web design: what is saturation?

Different perspectives on color lead to self-tutoring: the tutor shares ideas about saturation.

Saturation is the opposite of gray. (See my post here about gray and grayscale.) Gray can also be written grey (see my post here). However, my sources about color seem to prefer the spelling gray, so I follow their lead.

Saturated means “pure color”. I’ve, at times, imagined “saturated” color as dark or vivid. In some cases the perception makes sense, from a practical point of view.

In the rgb (red, green, blue) system, gray is an equal combination of all three. Therefore, a color can be imagined to exist “on top of gray”. For example, the css color chocolate, versus its saturated counterpart:

chocolate background

chocolate background, gray subtracted:
“saturated” chocolate

Art, web design: gray and grayscale, part 0

Self-tutoring about color theory. The tutor mentions gray and grayscale.

From the red, green, blue (aka rgb) point of view, gray is composed of equal inputs from each. There are many lightnesses of it.

gray: rgb(n,n,n)

Any flavor of gray is on the grayscale.

Gray is not a color.
