Summer color palette

No uploadRuns in your browserReviewed October 10, 2026

Short answer

A summer palette from real photographs: the three Wikimedia Commons photos we used (Rügen, Beach at Sellin -- 2009 -- 1173; 2012 Summer Olympics - Beach volleyball; P.S. Krøyer - Summer evening on Skagen's) gave these six colors, most common first: #8293AB (24%), #9E9789 (19%), #B8BBBF (18%), #666267 (17%), #302931 (13%), #DFE0E1 (9%).

Nothing is uploaded. The picture is shrunk to 320 pixels wide in your browser and the colors are found there.

Key takeaways

  • The summer palette from 3 photographs is #8293AB, #9E9789, #B8BBBF, #666267, #302931, #DFE0E1.
  • The most common color, #8293AB (24% of the pixels), is 5.0 CIEDE2000 units from the CSS color lightslategray.
  • The closest two colors of the palette are 9.2 apart (about 1 is a just noticeable difference); for protanopia 9.1, deuteranopia 9.2, tritanopia 9.2.
  • Black text on #8293AB has a contrast of 6.7:1 and white text 3.1:1; black text passes AA.
  • Each photograph alone gave five colors: the lists are in the table, with the photographer and license.
  • The complement of #8293AB is #AB9A82; the analogous pair is #82A7AB and #8582AB.

Measured: the summer palette

The most common is #8293AB, which is close to the CSS color lightslategray (#778899). The two closest are 9.2 apart on the CIEDE2000 scale; under deuteranopia the closest pair is 9.2 apart.

We searched Wikimedia Commons for photographs of the theme and kept photographs under Creative Commons or public domain licenses. For this theme we took the first three results. The tool's own palette code (k-means in CIELAB, no random numbers) found five colors in each photograph. The six colors in the table below come from all pixels of the three photographs.

The three photographs together: six colors, most common first.

Summer appears here as near lightslategray, near darkgray, near silver, near dimgray, near black, near gainsboro. The photo palette is a starting point: colors from a photograph are rarely pure, and the table shows how each performs as text on white and black.

Check the contrast before you use it for text

  • Summer #8293AB on white: 3.13:1; on black: 6.71:1.
  • The darkest shade in the table, #0D0F11, reaches 19.20:1 on white.
  • Large text (at least 18 point, or 14 point bold) needs 3:1; normal text needs 4.5:1; the enhanced level needs 7:1.
  • Do not use color as the only way to tell things apart: about 1 in 12 men have a color vision deficiency.

How the numbers were made

The hex value of each color comes from the photographs. Harmonies rotate the hue in HSL and keep saturation and lightness. Contrast follows the WCAG 2 definition with relative luminance. Color differences use CIEDE2000, which Wikipedia notes is designed so that a difference of 1.0 stands for a just noticeable difference. Color blindness is simulated with the matrices of Machado, Oliveira and Fernandes (2009) at severity 1.0. Palette extraction: pixels are grouped into 32 levels per channel and clustered with k-means in CIELAB; the same picture always gives the same palette. The accuracy test on pictures of known colors is on the palette generator page.

Questions people ask

What are good colors for a summer palette?

From our three photographs: #8293AB, #9E9789, #B8BBBF, #666267, #302931, #DFE0E1.

Where do these colors come from?

From 3 Wikimedia Commons photographs under Creative Commons or public domain licenses; the table lists each one.

Is #8293AB accessible for text?

On white it has 3.13:1 and on black 6.71:1. The WCAG AA minimum for normal text is 4.5:1, so black text on #8293AB passes.

Can people with color blindness tell the summer palette apart?

For the six colors of the photo palette, the closest pair is 9.2 apart for typical vision and 9.2 for deuteranopia (CIEDE2000; below about 10 is hard).

How was the palette made?

The tool found the dominant colors of the photographs with k-means clustering in CIELAB. It runs in your browser; you can do the same with your own picture on the palette from image page.

Can I use these colors commercially?

Colors themselves are not licensed. The photographs used to find them keep their Creative Commons licenses, shown in the table.

Can I get a palette from my own photo?

Yes. Use the palette from an image tool; nothing is uploaded.

How many colors should a palette have?

Many designs use five: one dominant, one or two supporting, one accent and a neutral. The tool lets you choose 3 to 10 when you extract from a picture.

What is the difference between tints and shades?

A tint mixes the color with white and a shade mixes it with black. The table shows nine of each in steps of 10%.
