What Colors Go with Very Dark Azure? Color Pairing Examples to Give Deep Sky Blue a Refined Look [#172A36]

Very Dark Azure (■#172A36) is a near-black color that retains a deep sky-blue tone with a slight blue-green cast. On a website, it works well for headers, hero sections, and footers when you want a calm cool palette, but relying only on dark blues can make boundaries between information harder to see. This article pairs ■#172A36 with cool ivory, smoky azure, and sand beige to give the deep sky blue a refined, orderly look.

Pair it with cool ivory, smoky azure, and sand beige

One practical combination for ■#172A36 is a light cool ivory ■#EAF2F4, a smoky azure ■#86A9B4 that stays within the cool family, and a subdued sand beige ■#C1A47A.

■#EAF2F4 creates a large brightness difference from the base color, so it works well for headings and body text on dark areas and as the background of light information surfaces. ■#86A9B4 keeps the blue-green relationship while adding lightness, making it useful for supporting text or thin separators. ■#C1A47A moves away from the cool side toward a low-saturation warm tone, so it can distinguish a primary button or small label without becoming as forceful as a vivid orange.

Giving the colors clear roles as a light information surface, a related middle tone, and a restrained warm accent helps preserve the calm character of ■#172A36 while creating the brightness differences the page needs.

Use the deep sky blue for structure and keep reading surfaces light

When ■#172A36 is the base color, it is usually easier to use when the dark tone is concentrated in the header, hero section, or footer rather than spread across the entire page. Long passages and numeric information can then move onto a lighter surface.

A contrast ratio describes the difference in relative brightness between a foreground element and its background. The ratio is about 13.02:1 for ■#172A36 with ■#EAF2F4, 5.88:1 for ■#172A36 with ■#86A9B4, and 6.23:1 for ■#172A36 with ■#C1A47A. Under WCAG 2.2, normal text needs at least 4.5:1 contrast. Visual information required to identify interface components or meaningful graphics needs at least 3:1 contrast against adjacent colors. The text pairs shown on the dark base meet the 4.5:1 threshold.

By contrast, ■#86A9B4 on ■#EAF2F4 is about 2.22:1, and ■#C1A47A on ■#EAF2F4 is about 2.09:1. Neither should be used for normal body text on that light background; switch body text to a sufficiently dark color such as ■#172A36.

For a refined look, limit the number of cool tones and keep warm accents small

If you want ■#172A36 to feel refined, it is generally easier to give the base color, light surface, and supporting tone clear roles than to add many steps of similar blue-green. Keep ■#86A9B4 for supporting information or separators, while the main reading experience relies on the stronger light-dark difference between ■#EAF2F4 and ■#172A36.

Reserve ■#C1A47A for a primary action, thin line, or small label so it adds a little warmth to the cool palette without taking over the page. If photography or product images already contain a lot of blue-green or beige, avoid adding more supporting colors and adjust the amount of light information surface instead.

In HueRoll, you can enter ■#172A36 as a HEX value. HEX is one way to represent a web color using a code that begins with #. You can explore related colors and palette suggestions and compare the selected color with white or black. HueRoll does not compare arbitrary color pairs or automatically determine WCAG conformance levels, so the pairwise contrast ratios in this article were calculated separately.
