Harmony and structure
Four hues are spaced around the wheel in two complementary pairs. It is the richest scheme, and the hardest to balance.
In this palette the hues fall in the green, cyan, magenta, orange and teal families, spread across 274 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: 1 of its 5 chromatic colors lean warm and 1 lean cool. Its average chroma of 0.068 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 Slate (#587255) with Ink (#011E1C) at a contrast ratio of 3.28:1, 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 (#011E1C), so this page suggests #E3F9E0 for text, a lightened Slate that reaches 15.69:1. Check any pair you use in the contrast checker.
Under protanopia (reduced red sensitivity), #391C0E and #011E1C may look alike, so avoid using that difference alone to carry meaning.
How to use it
Suggested roles: #011E1C as the background, #391C0E for cards and surfaces, #571965 as the primary brand color, #2B5B71 as the accent, and #E3F9E0 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.
Let one hue take most of the space and use the others sparingly. Control the mood with lightness and saturation rather than hue.
