In this palette the hues fall in the blue family, spread across 13 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 Sapphire (#3C69B8) with Navy (#01122B) at a contrast ratio of 3.47:1, 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.

Under tritanopia (reduced blue sensitivity), #3A4E7E and #023F77 may look alike, so avoid using that difference alone to carry meaning.
How to use it
Suggested roles: #01122B as the background, #3A4E7E for cards and surfaces, #023F77 as the primary brand color, #162651 as the accent, and #EBF2FE for text (a computed lighter shade of Sapphire, 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 lightest color for large areas, the mid tones for structure, and the darkest for text. Add contrast through lightness, since hue will not do it for you.
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.
