About this palette
Shadow Plum Delta is palette number 14,989,563 of Tintly's fifteen million generated palettes. It is a dark palette built on a tetradic scheme, and it is anchored by Plum (#6B3586), the most saturated of its five colors.
The palette reads as deep, dramatic and immersive. Its colors run from Slate (#346C7F) at the light end to Navy (#07103B) at the dark end, covering 20% to 50% 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 cyan, violet, red, green and blue families, spread across 271 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 2 lean cool. Its average chroma of 0.096 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 (#346C7F) with Navy (#07103B) at a contrast ratio of 3.13:1, 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 (#07103B), so this page suggests #E0F6FF for text, a lightened Slate that reaches 16.39:1. Check any pair you use in the contrast checker.
Under protanopia (reduced red sensitivity), #6E2602 and #173300 may look alike, so avoid using that difference alone to carry meaning.
How to use it
Suggested roles: #07103B as the background, #6E2602 for cards and surfaces, #6B3586 as the primary brand color, #173300 as the accent, and #E0F6FF 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.
