How to use it
Suggested roles: #001912 as the background, #134246 for cards and surfaces, #12576A as the primary brand color, #052F2E as the accent, and #E5F4FE 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 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.
