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.

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?

background: rgb(220,245,245)

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, gray subtracted:
“saturated” chocolate

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.

Art self-tutoring: the tutor inquires about the difference between baby blue and powder blue.

This background is baby blue,

Tutoring web design, color is a focus. The tutor mentions analogous colors.

One point of view about color imagines a “color wheel”. The wheel is divided into thirds, one for each of the primary colors red, yellow, and blue. Between the primaries are mixes:

An analogous color set is one that occupies no more than one continuous third of the color wheel. Therefore, pink to orange or purple to teal might be examples of analogous color sets.

Tutoring web design, you might encounter other color systems besides rgb. The tutor begins about hue.

Hue exists on a scale from 0 to 360 degrees:

• 0 is red
• 120 is green
• 240 is blue

Between those values are combinations of them: 30 degrees is orange, for instance, while 330 is hot pink.

Hue alone doesn’t constitute a color, because the color depends on the hue along with saturation and lightness (or intensity or value, depending on the system).

Hue-based color systems constitute a huge, complex topic to which I’ll be returning:)

Tutoring, you’re interested in education. The tutor brings up two business titans from the late ’90s/2000s: What were their first degrees?

In their time, I followed both Carly Fiorina (CEO, Hewlett-Packard, 1999-2005) and Martha Stewart through the headlines. Both were tremendous achievers – that’s an understatement.

Interestingly, both have arts degrees (among others). Carly has a BA in philosophy and medieval history from Stanford; Martha has a double major in history and architectural history from Barnard College.

Some people say it’s hard to succeed in business with an arts degree….:)

The tutor further explores the golden ratio.

In my previous posts here and here, I’ve discussed some aspects of the golden ratio. Trying to find other special facets of it, I’ve dreamed up color combinations that express the golden ratio between colors:

Recalling that the golden ratio is approx. 162:100, behold the following color mixes:

100 red: 162 blue

162 red: 100 blue

162 red: 100 green

100 red: 162 green

162 green: 100 blue

100 green: 162 blue

If you feel something special in these color combinations, it’s possibly attributed to the golden ratio:)
