Pastel color palettes: how to use them without looking washed out

Updated 2026-09-12 · by the ColorSwoop team

Pastels are the easiest colors to like and the hardest to use well. Here is the formula that keeps them soft without going flat.

What a pastel actually is

A pastel is any hue pushed toward white: high lightness, gentle saturation. In OKLCH terms our pastel collection keeps every color above 70% lightness and below 0.13 chroma. That definition matters because it explains the main problem: pastels have almost no contrast with each other.

The three mistakes

  1. Pastel on pastel text. Lavender text on mint background looks lovely in a swatch and is unreadable on a phone in sunlight. Every pastel palette needs a deep anchor for type.
  2. No hierarchy. Four pastels at the same lightness fight for attention. Vary lightness: one near-white, two mid pastels, one slightly deeper.
  3. Too many hues. Pastels already look playful; five different hues tip into nursery. Two or three hues plus a warm neutral is enough.

The formula: base, anchor, accent

Open any palette on ColorSwoop and scroll to Why it works: the roles above are assigned automatically and the contrast ratios are listed, so you can see immediately whether a pastel set needs an anchor.

Pastel combinations that always work

Checking accessibility

Paste your text and background into the contrast checker. If a pastel pair fails, darken the text color rather than saturating the pastel; the tool suggests the nearest passing shade.

FAQ

What makes a color pastel?

High lightness (roughly 75-92% in HSL) combined with low to medium saturation. Technically a pastel is a hue mixed with a lot of white, which is why pastels feel soft and airy.

Do pastel palettes work for text?

Not on their own. Two pastels rarely reach the 4.5:1 contrast required for body text. Pair pastels with a charcoal or deep version of one of the hues for text and icons.

Which pastel combinations are most popular?

Blush pink with sage, lavender with mint, peach with sky blue, and butter yellow with lilac. Browse the pastel collection for hundreds of tested combinations.
