What Accent Colors Go with Navy? Color Pairing Examples for Making Accents Stand Out

When navy is the main color and you want an accent to stand out, a lighter mint can work well when used in a small area. This example pairs navy ■#243A5A with mint ■#77C8B5 as the accent. Body text uses charcoal ■#2B3138, the page background uses off-white ■#F7F6F2, and supporting panels use pale blue-gray ■#E7EBF0. This separates the roles of the dark main color and the lighter accent.

Use a light mint accent within dark navy areas

■#243A5A is a dark, subdued blue, so another dark accent may not create much separation. Here, ■#77C8B5 is used instead. The contrast ratio (a measure of the relative brightness difference between foreground and background colors) between the navy and mint is about 5.86:1. Because they differ in both hue (the basic family of color, such as red, blue, or green) and lightness, short labels and primary actions can be distinguished more clearly within a navy section.

The page background ■#F7F6F2 and body text ■#2B3138 have a contrast ratio of about 12.14:1. Using ■#243A5A as a background with ■#FFFFFF text gives about 11.49:1. Keeping navy as the larger area and mint as a smaller accent helps make the accent’s location intentional.

On a SaaS case-study page, use mint for outcome labels and the CTA

For a B2B SaaS case-study page, use ■#243A5A for the hero section, with ■#FFFFFF for the headline and customer name. Use ■#F7F6F2 for the body area and ■#2B3138 for the text describing the challenge and implementation background.

Within the navy hero, short labels such as “Key Takeaway” or “Outcome” can use ■#77C8B5 as the background with ■#243A5A text, giving about 5.86:1. The main “Download the Case Study” button can use the same combination. On the navy surface, this provides sufficient contrast for both the button text and the button boundary.

For supporting sections such as customer comments or an implementation flow, use ■#E7EBF0 with ■#2B3138 text, which gives about 10.97:1. A small heading in ■#243A5A on the same surface gives about 9.60:1.

WCAG (Web Content Accessibility Guidelines) 2.2 requires at least a 4.5:1 contrast ratio for normal-size text. Non-text information needed to identify controls or important boundaries uses a 3:1 minimum against adjacent colors.

To make the accent stand out, do not spread mint across light backgrounds

■#77C8B5 against ■#F7F6F2 has a contrast ratio of only about 1.81:1, and against ■#E7EBF0 it is about 1.64:1. Avoid using mint as normal-size text on those light surfaces or as the only cue for an important boundary. On lighter areas, use navy ■#243A5A for text or borders, and keep mint primarily within navy sections where its role is clearer.

When making an accent stand out against navy, adding more colors is usually less useful than limiting where the accent appears and what it does. In HueRoll, you can enter ■#243A5A and review complementary and analogous colors, palette suggestions, and the selected color’s contrast with white and black. HueRoll does not compare arbitrary color pairs or automatically judge WCAG AA or AAA conformance, so the two-color ratios shown in this article were calculated separately.
