What it is

Happy Hues by Mackenzie Child presents a set of hand-picked colour palettes, each applied to the site itself so you see it in use, with notes on which colour is for backgrounds, headlines, buttons and highlights.

Why it’s here

The explanations of what each colour is for are the valuable part. It teaches you to think in roles (background, paragraph, button, stroke) rather than just picking pretty colours.

Best for

  • beginners choosing colours
  • understanding colour roles
  • palette inspiration

Can my agent use this?

Agent limited agent friendliness

As a reference. Copy the hex values and the role of each colour into your prompt: "background #..., headline #..., button #...".

Limited: Mainly a visual reference. Great for humans and for describing a direction, but there's little an agent can read or install.
