In this palette the hues fall in the cyan, blue and violet families, spread across 60 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.

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 Teal (#036F8C) with Navy (#170D42) at a contrast ratio of 3.11:1, 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 (#170D42), so this page suggests #E2F6FE for text, a lightened Teal that reaches 16.07:1. 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: #170D42 as the background, #212943 for cards and surfaces, #023582 as the primary brand color, #0C5886 as the accent, and #E2F6FE for text (a computed lighter shade of Teal, 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 lead and let the others support it. Keep one color noticeably lighter or darker than the rest so the layout has a clear focal point.
Typical uses for a dark palette include dark-mode interfaces, gaming and music apps, luxury packaging and cinematic presentations. Open it in the generator to lock the colors you love and reroll the rest, or in the visualizer to see it on real layouts.
