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 yellow, blue and violet families, spread across 222 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 temperature-balanced: 2 of its 5 chromatic colors lean warm and 1 lean cool. Its average chroma of 0.082 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 deep, dramatic and immersive.
Accessibility and contrast
The strongest pairing is Olive (#756D41) with Ink (#1D1200) at a contrast ratio of 3.53:1, 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 (#1D1200), so this page suggests #F8F3D5 for text, a lightened Olive that reaches 16.48:1. 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: #1D1200 as the background, #0A3E69 for cards and surfaces, #38115B as the primary brand color, #54570D as the accent, and #F8F3D5 for text (a computed lighter shade of Olive, 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.
