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.

I like that definition, it's a little broader and encompasses more pixel art.

Maybe we should eventually use all this for a wiki.

Making some kind of site from it sounds good.

Personally, I don't have the same trust in wikis that I once did -- in particular, my impression is that the more room for subjectiveness in the topic, the worse a wiki functions. I think a site whose content is generated from a github repo curated by a small team, that of course anyone can submit pull requests to, is a model that would do better at creating a trustworthy resource of consistent quality.
If you insist on being pessimistic about your own abilities, consider also being pessimistic about the accuracy of that pessimistic judgement.

i actually like the forum approach, as it doesnt disconnect content from the discussion. I was a member of the gpwiki before, and that just fell apart, because it split the community up. Not a fan of that.
And with the tagging system i suppose we can have a sort of overview or index page for tutorials and other articles like that, which would be kinda cool.

I like Ai's idea of a curated github.

Updated op with a bunch of links (still lots of stubs/bullet points left to fill with details).

Changed the "Color" entry to emphasize that the concepts described in there are of emotional nature and not meant to describe the physical process of any color mixing theory nor the scientific property of color temperature.

Added entry for Color Gradient, Color Ramp, Color Shift.

* Are those supposed to all be synonyms? In that case, I guess Hue Shifting is being covered separately, perhaps in the Hue entry?

* I assume you are aware that there are other color spaces that can be usefully used for calculating gradients (HSL, LAB, LCH), as well as linear RGB versus sRGB, and just left them out to keep things simple?

* The term 'lightness' is associated with HSL channel L, which may be confusing in this context. I believe you used the term 'brightness' (which has no association with any particular colorspace AFAIK) in an earlier entry.
