Harmony and structure
One hue is paired with the two hues flanking its opposite. You keep most of the energy of a complementary scheme with less tension and more variety.
In this palette the hues fall in the blue, red and yellow families, spread across 224 degrees of the OKLCH hue circle. Dark palettes keep chroma between 0.04 and 0.14, and lightness between 20% and 52%, which is why the set feels consistent.
Temperature and mood
Overall the palette is cool: 1 of its 5 chromatic colors lean warm and 3 lean cool. Its average chroma of 0.072 makes the saturation balanced.
That combination suits dark-mode interfaces, gaming and music apps and luxury packaging, and it is a good fit when you want a design to feel nocturnal, focused and cinematic.
Accessibility and contrast
The strongest pairing is Navy (#001A37) with Slate (#176C99) at a contrast ratio of 3.02:1, which is WCAG AA large. Across all 10 possible pairs, 0 reach the 4.5:1 AA level for normal text and 1 more reach 3:1 for large text.
No other palette color reaches 4.5:1 on the background (#001A37), so this page suggests #E5F4FF for text, a lightened Slate that reaches 15.55:1. Check any pair you use in the contrast checker.
All five colors stay distinguishable under protanopia, deuteranopia and tritanopia simulations, which is a good sign, although it is no substitute for testing with real users.
How to use it
Suggested roles: #001A37 as the background, #585328 for cards and surfaces, #542C1B as the primary brand color, #1B2747 as the accent, and #E5F4FF for text (a computed lighter shade of Slate, because no palette color is readable on that background). A reliable starting split is 60% background and surface, 30% primary and 10% accent.
Use the lone hue as the dominant brand color and the two flanking hues as secondary and accent colors.
