Added entries for Palette Effect, Palette Structure and Palette Swap.

---

Palette Effect
In Indexed Images/Modes where each pixel in the image refers to a specific color in a sequence of colors(=palette) (instead of holding the full definition of the color in each individual pixel itself), a number of visual effects such as Color Cycling and Color Fading can be achieved by manipulating the palette instead of manipulating the pixels themselves.

This was used a lot on old hardware as manipulating the definition of colors in the palette took much fewer CPU cycles than going through the image and changing the actual pixels themselves.

A simple example for a Palette Effect is just re-defining a color in the palette:
If a thousand pixels in an image referred to color at index five in the palette and index five would hold Green and index twelve would hold Red, all thousand pixels could be changed to Red by changing the color at index five from Green to Red instead of going through the image and looking for every Green pixel and changing the pixel itself to refer to index twelve.

Added History Of Pixel Art, Index Painting and Color Cycling.


History Of Pixel Art
see The History Of Pixel Art


Index Painting
Creating Pixel Art in Indexed Modes, working with Indexed Images while paying attention to Palette Structure and keeping possible Palette Effects in mind and at all times keeping control over (if necessary by fixing the results) the pixel level polish of a piece even when using tools that influence more than one pixel at a time.

Historically, "Index Painting" is the natural way to go and think about making Pixel Art as most hardware and digital image editing tools either used Indexed Modes as the default mode or simply did not provide any other modes. The term "Index Painting" was not around then because there simply was nothing else. Today the term seems to be used to set "Pixel Art"(in the sense of Index Painting) apart from other "Pixel Art"(in the sense of Digital Painting and Computer Generated Imagery(e.g. 3D renderings)) and the third kind of "Pixel Art"(the purists "one pixel at a time"- process).

Some advocate placing one pixel at a time as the only "allowed" process to create "Pixel Art"(a term which eludes definition itself) while others advocate whether something is or is not "Pixel Art" can not be defined by processes but only by looking at the results.

The actual term "Index Painting" emerged from the on-going online debate about "pixel purism", processes and results:

Updated entries for Construction and Dithering & Dither-AA (and removed version number as the board already shows when a post was last edited).

Reminds me of thumbnailing, which is sort of proto-composition, proto-construction and proto-gesture all rolled together. Which makes me think of the fact that gesture typically refers to the posture of an animate creature, but can usefully be applied to any organic object (and arguably many non-organic ones, or even the picture as a whole.).. and wonder if you are going to point out in the gesture entry that gesture is not restricted to animate things.
If you insist on being pessimistic about your own abilities, consider also being pessimistic about the accuracy of that pessimistic judgement.

Yeah, Gesture really works for anything organic or not. I think the specific term Gesture however came from figure drawing, living creatures and animation so it should refer to that even if it is related to the "other" use. Not sure what the other use is called though: Maybe Rhythm & Flow = Gesture for everything which is not a living being?

I thought Thumbnailing is the same as sketching/doodling but on a very small scale to figure out composition/partitioning/placement/etc. quickly and to make lots of iterations fast without having to worry about the details that go into creating a polished artwork from it.

I guess so. My experience of thumbnailing is that you can put anything that reads and conveys a quick useful impression (in a 1"..2" picture size) in them. Gesture of the focal figure(s) might be included - IME it's usually central.
If you insist on being pessimistic about your own abilities, consider also being pessimistic about the accuracy of that pessimistic judgement.

As someone who has just gotten into pixel art and doesn’t really know much of the terminology yet, this has been extremely helpful. Thanks for posting this.

Thank you both, Student of the Pixel and Helm. Just dropping in to report that I have starting porting this glossary to a proper wiki at http://paag.dennisbusch.de which will make maintenance and expansion much easier.

So the glossary in the first post of this thread will not be updated anymore. I will still watch this thread for suggestions on terms that should be included in the glossary.
