The Physics of Luxury
Walk into an Apple Store. Walk into a luxury jewelry shop. What do you see? Black backgrounds. Directed lighting.
Darkness creates focus. It eliminates distraction. On OLED screens, black isn't a color—it's the absence of light. It saves battery and signals 'Premium'.
The Contrast Trap
The biggest mistake designers make: Using pure black (#000000) and pure white (#FFFFFF). This creates 'halation' (blurring) for users with astigmatism.
**Professional Dark Mode** uses Dark Grays (#121212) and desaturated text colors. Test your contrast here:
