Color, explained
Short pieces about the parts of colour that quietly cause trouble: values that disagree between tools, formats that look identical and are not, and what actually happens to a photograph when a palette is pulled out of it. Each one describes the same maths the PaletteViva tools run, so what you read here is what the software does — and every guide ends at the tool that applies it.
From image to value
- How image palette extraction works Why averaging pixels in RGB returns mud, what quantisation actually does, and how a medoid guarantees every swatch is a colour genuinely in your image. If you have ever wondered why two extractors disagree on the same photo, this is the piece.
- sRGB vs Display P3 Phones shoot Display P3, browsers read sRGB, and the gap between them is why a sampled hex can look wrong in Photoshop. Includes the subtler trap: sampling an image a canvas has quietly resized.
- Hex code from a screenshot A step-by-step for getting an exact hex from an iPhone screenshot — where to tap, when the value disagrees with your design tool, and what the Android route looks like.
These pieces pair with the palette extractor and the image color picker , which read real pixels out of your own pictures.
Formats and color spaces
Every format the guides mention can be typed straight into the color converter .
Everything described here is implemented in the tools themselves — no article is needed to use any of them, and none of them will make you do the arithmetic. See all the tools .
