About this palette
Nocturnal Graphite Umbra is palette number 827 of Tintly's fifteen million generated palettes. It is a dark palette built on a tetradic scheme, and it is anchored by Graphite (#2B375E), the most saturated of its five colors.
The palette reads as deep, dramatic and immersive. Its colors run from Slate (#726543) at the light end to Ink (#091905) at the dark end, covering 19% to 51% perceptual lightness, so it has real range rather than five similar tones.

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 yellow, teal, blue, rose and green families, spread across 269 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 0.061 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 (#726543) with Ink (#091905) at a contrast ratio of 3.17:1, 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 (#091905), so this page suggests #FCF1D4 for text, a lightened Slate that reaches 16.19:1. 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: #091905 as the background, #135B52 for cards and surfaces, #2B375E as the primary brand color, #471D2B as the accent, and #FCF1D4 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.
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.
