Under protanopia (reduced red sensitivity), #496C6D and #0D616A may look alike, so avoid using that difference alone to carry meaning. Under tritanopia (reduced blue sensitivity), #496C6D and #0D616A may look alike, so avoid using that difference alone to carry meaning.
How to use it
Suggested roles: #001F20 as the background, #013137 for cards and surfaces, #0D616A as the primary brand color, #004548 as the accent, and #D4FBFC 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.
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.
