The seasonal palette generator maps spring, summer, autumn and winter onto four fixed hue runs, giving season color palettes that are fully deterministic — the same season always returns the same five swatches.
What is Seasonal Palette Generator?
This page is the exception in the random-palette family: nothing about it is rolled. Each season owns a fixed run of five hues, and every swatch is placed with a lightness cycle of 0.55, 0.67, 0.79, 0.55 and 0.67 at a constant chroma of 0.14. Choose a season and the strip is rebuilt from those numbers; choose it again tomorrow and you will get the same result. That makes a seasonal palette generator unusually useful for anything a design system has to reproduce.
- Spring — hues 80, 110, 50, 160 and 200: yellow-green, green, gold, teal-green and blue.
- Summer — hues 200, 220, 180, 30 and 60: two blues, a cyan, an orange and a yellow.
- Autumn — hues 25, 40, 15, 60 and 350: rust, ochre, brown-orange, mustard and a red-pink.
- Winter — hues 240, 260, 220, 280 and 200: indigo, violet, blue, purple and cyan-blue.
The lightness cycle is what gives each run its rhythm. Because it repeats across five slots, the first and fourth swatches share a lightness, the second and fifth match, and the third sits alone at the lightest value — so each season's strip has a peak in the middle and a pair of parallel values either side, rather than a single monotonically rising ramp. Chroma is constant at 0.14, which is vivid enough to read as a season and muted enough that the four runs feel like members of one family rather than four unrelated palettes.
- Only four presets, and no way to adjust hue, lightness or chroma from the page.
- The runs are untitled set lists rather than sampled photographs, so they read as a season's colour family rather than as a month's palette.
- Nothing in any run is dark; no text colour and no deep surface is supplied.
- No export beyond copying individual hex values, and no CSS block on this page.
It is worth being explicit about what the determinism buys. A deterministic season palette can be written straight into a stylesheet as constants and reviewed like any other token, whereas a rolled palette has to be captured before anyone can discuss it. Because the four season color palettes share a chroma and a lightness structure, they also behave consistently as a family: a component styled for spring will not break when the theme switches to winter, which is the property a rotating theme actually needs.
Use it for editorial and campaign work that has to be consistent across a year, for product themes that change with the calendar, and anywhere a seasonal rotation should be recognisable rather than constantly new. Because the values never change, they can be written into a stylesheet as constants; the spring summer autumn winter colors then behave like tokens rather than like rolls. Where the palette itself should be random, use the random or daily generators instead, and where a specific season needs more depth, take one value into the shade and tint tools.
How to use Seasonal Palette Generator
- Choose a season from the dropdown; the strip rebuilds from that season's fixed hues.
- Read the five swatches, noting that lightness peaks at the third and repeats elsewhere.
- Copy the hex values you need — they are stable, so they can safely become tokens.
- Add a dark tone from the shade tools if the palette has to carry text.
When to use Seasonal Palette Generator vs related tools
Use this when a palette has to be reproducible across a year of campaigns or themes. The random palette generator is the unconstrained alternative, the tints generator and shades generator add the depth no season run contains, and the CSS variables generator turns a chosen season into named tokens.
