Digital color theory is a mysterious black box that few resources bother explaining, but how does it all work? Where did it all come from? And why are the color pickers in the art programs you use so bad?

Topics covered include: Quantization, color banding, dithering, value mapping, palette swapping, radiometry, photometry, how humans perceive color, colorimetry, spectral rendering, the rgb color model, deriving srgb, the hsl color model, gradient mapping, randomly generated color palettes, perceptual color spaces, the lab color model, oklab

Use the palette generator here:
(sorry website is down for the foreseeable future but there are much better color palette generators you can find lol this was for an experiment not meant to be used as an actual service)
