What Is a Rainbow Color Palette?

Rainbows are an optical illusion, a result of the reflection, refraction, and dispersion of light in water droplets. A multicolored arc appears in the sky, showcasing a breathtaking spectrum of colored light.

While a rainbow features the whole spectrum of color in a smooth graduation, to the human eye, a rainbow appears to be made up of bands of color. The most commonly cited sequence of colors are the seven hues identified by Isaac Newton—red, orange, yellow, green, blue, indigo, and violet­—made memorable by the mnemonic Richard Of York Gave Battle In Vain (ROYGBIV).

While traditional rainbow color schemes follow this seven-color sequence, you can also apply the rainbow principle to a variety of different palettes, giving a fresh twist on multicolored, sequential schemes.

Alternative rainbow palettes generally range from warm to cool colors, building a graduating rather than contrasting sequence. Rainbow palettes also usually incorporate more colors than a standard scheme, to achieve a completely multicolored effect.  

Scroll down to discover ten palettes that offer a new twist on the traditional rainbow scheme—from sugar-sweet iridescents to tropical and Modernist-inspired rainbow palettes.


What Is the Symbolism Behind Rainbow Schemes?

Rainbow color palettes have been highly symbolic throughout recent history, from the rainbow icon adopted by supporters of the National Health Service in the UK during the pandemic, to the “rainbow nation” slogan given by Nelson Mandela to the newly democratic South Africa.

Famously adopted by the LGBTQ+ community as a symbol of diversity in the 1970s, rainbow palettes are now omnipresent during gay pride events worldwide. With each color symbolic of an aspect of the queer community, the Pride rainbow flag uses six colors—red, orange, yellow, green, blue, and violet.

In the design world, the optimistic appeal of rainbows has led many businesses to adopt a multicolored approach in their branding and products. Apple’s first incarnation of its iconic logo featured a rainbow palette, chosen for the fact that the Apple II (released in 1977) could display color images, a rarity for the time. Apple has revisited its multicolored past with the recent release of the new twenty-four inch iMac in seven colors.

Other brands that have used rainbow palettes in their brand identities include NBC, IBM, Polaroid, and (of course) Skittles, who use the slogan “Taste the Rainbow” in their marketing and advertising.

5. Modernist Rainbow

If you prefer bold color-blocking to a traditional rainbow palette, this scheme blends the two approaches together, creating a bold and painterly effect that wouldn’t look out of place on a Bauhaus poster. Limit your hues to just this bold group of four to achieve more contrast and, therefore, a stronger color-block effect.

6. TV Rainbow

Although color technology has developed in leaps and bounds over the past few decades, at its core is the simple use of red, green, and blue light, combined to create a full color spectrum. This palette is inspired by the TV-friendly colors that characterized the style of the 1980s. Punchy, graphic, and rich, these have a more contemporary edge when teamed with black or white.

Perhaps you’re looking for a more chilled-out alternative to a high-octane rainbow palette.

8. Pastel Rainbow

Sugar-sweet and surprisingly modern, pastel rainbows don’t have to be limited to children’s branding alone. A rainbow of pastel tones combines an innocent, nostalgic mood with the upbeat personality of multicolored palettes. Although this candy-hued scheme would be a natural fit for children’s designs, it would also be an effective palette for summer-themed marketing.

Many individuals associate rainbow color schemes with childhood, with one reason being that colorful palettes are often the backdrop to summer vacations and family resorts.

This palette would be a cheerful scheme for tourism businesses, cafés, or holiday activities.

The tropics are where rainbow schemes are realized on the forest floor—from multicolored macaws to resplendent quetzals.

This palette is summery and soothing, and would make a lovely match for nature-inspired designs or eco branding.
