Happy Hues shows curated color palettes applied to a live mock website, background, headline, button, and card, rather than isolated swatches, so you see how a palette actually looks in context before using it.
Every color in a palette gets applied to a real page layout at once, which surfaces problems (like a button color that disappears against a background) that a swatch grid alone never reveals.
Designers who want to preview a palette in a realistic layout before committing, not merely as a strip of disconnected color chips.
The color encyclopedia section is worth a look for anyone still learning color terminology (hue, tint, shade), not merely for picking a palette.
Curated colour palettes shown in real UI context, not just swatches.
