Swatch
A small sample that shows one color.
Choose colors from a wheel or photograph, then test them in the same design.

Recolor one existing poster with a small role-labeled palette and compare the same content before and after.
Start with one of the four posters from Give each color a clear job. Keep the original intact. Three separate palette mini-studies are optional exploration, not another completion route.
A small sample that shows one color.
The color with the largest or strongest presence in the design.
A color used in a few places to make something stand out.
The code your design tool uses to save the exact color.

For example“The dark heading is easier to find” explains what changed for a reader.
For exampleRecord the exact color code so the same yellow appears on every button.
Worked swatches. A swatch is one color sample; a palette is the chosen set. On the same poster, write Background #…, Main text #…, and Accent #… beside three samples. Compare the actual foreground/background text pair in a contrast checker, record the ratio, and adjust the pair if reading suffers. The relationship on the wheel and the color’s job are different descriptions.
