Or in other words, like brightness, temperature is a scale. Some colors are warmer than others, even if both are "warm". A neutral color next to a dark color is considered bright, just like a neutral color next to a cold color is considered warm.
Yeah, this is the opponent process (which is biological, rather than psychological -- your color perception being tired by more intense colors and being distorted in the opposite direction as a result). It's a primary cause of the "newbie art is oversaturated, pro art is understated in saturation" outcome, and IMO needs to be covered somewhere -- in color mixing, I guess.

The crappiness of HSV/HSL et al introduce further confusion into the subject: When you pick a bright yellow and darken it by dropping  V / L, it can become greenish (ie. cooler). But that's an artefact of the simplicity of that color model. Color models that actually try to be true to life, like LAB / LCH, do not have this issue: when you pick a bright yellow and drop L down, you get a pretty-much-as-expected brown, with very similar level of warmth. So HSV / HSL are not very good tools for discussing this subject.
If you insist on being pessimistic about your own abilities, consider also being pessimistic about the accuracy of that pessimistic judgement.

I came across a chronologically ordered set of color systems. I thought it was interesting, so figured I'd share it.

Ah, board is back up. Added that chronological overview of different color systems to the further reading section of the Color entry.

Also added a few new images and further reading entries on some of the previous entries.

new images:

I like these. Particularly the Perspective Projection one, which shows clearly the idea that a projected shape is essentially a combination of 2d graphs.

Suggestions:

* Parallel Projection: s/picuture/picture/
* "45 degrees" is like "ATM machine" -- oddly redundant. At least to me, it would make more sense to pick only one of "" and "degrees"

Fixed.

Such a great project. I look forward to see it all come together.

About scientific and emotional explanation: It's a bit blurry. Whenever we systemize something, to understand and explain it, make it methodical, we are unwittingly having one foot back in the scientific aspect. For example, to understand the human behaviour, one can look at the neurological and chemical setup, but also study the situational behaviour, and cultural/sociological/historical elements. From biochemistry to psychology to anthropology, it's all science, generating knowledge, with a different emphasis in research. So the moment we try connect emotion with colour in a chart, we are theorizing emotion, to make it usable for artwork. There is even a science to "fun". It sort of plays into Game Theory, and is important for game designers to realize, that a player experience can be planned better than by gut feel or happenstance.

Not really important or new to you, but I felt like talking a lil' about that, it's been on my mind.

I agree with the greater relevance of psychological colour than physical property description for art.

Everything is about everything and everything connects with everything. But... I honestly do not think a single lifetime is long enough to explore and discuss EVERYTHING. A Glossary is like a door to a rabbit hole and a very rough overview but individual parts of the rabbit hole itself are better mapped out in detail elsewhere.

Agreed. You handle this well. it wasn't a critique. just felt like musing on this a lil' on the side.

This glossary will be something very special and useful.

Was not received as critique, just felt like a good lead-in to re-explain the purpose and scope of the term "Glossary" to everyone who might also be reading along and maybe wondering why it's not overly detailed or why I'm not including everything everyone said or says.

Everyone's favorite term added. Cluster! I took the liberty to broaden the originally proposed definition from "equally colored connected pixels" to "perceptually connected" and in the same breath added super-cluster, sub-cluster and fragment as terms for the mind to think about when pondering how to shape, place and combine clusters. An interesting observation is that the relationship between any two neighboring (sub)clusters, both in shape and value, has an effect on the implied orientation and direction of both clusters.

Cluster

----------------------------------------------
A patch of perceptually connected pixels which
are part of the description of a shape, volume
or texture or any other element.

A cluster may be thought of as a fragment of
any element, as a sample of anything, as seen
by the eye or as imagined.

Shaping and shading a cluster gives direction
and orientation to the cluster itself which
also serves to give direction and orientation
to the element which the cluster aims to help
define.

Shadow and light on a cluster can be thought
of as individual (sub)clusters as well. Single,
perceptually separated pixels are not clusters
by definition.
