How should dark mode colors differ from light mode?

Dark mode colors should not simply be inverted. Surfaces go from light to dark, but text contrast and color saturation need adjustment too. Highly saturated colors can appear vibrant on light backgrounds but feel too harsh on dark ones. A good dark theme desaturates slightly and adjusts tones for readability.

What is the recommended background color for dark mode?

Material Design recommends #121212 as a dark surface baseline. Many modern design systems use values between #0f0f0f and #1e1e1e for the primary surface. Pure black (#000000) creates too much contrast and can cause eye strain on most displays.

How do I implement dark mode with CSS variables?

Define your light mode colors as CSS custom properties under :root, then override them inside a @media (prefers-color-scheme: dark) block or a .dark class. Frameworks like Tailwind CSS support a dark mode class strategy out of the box.

Should dark mode text be pure white?

Pure white (#ffffff) on dark backgrounds creates very high contrast that can cause fatigue in low-light conditions. Material Design and many other systems use off-white (#e0e0e0 or rgba(255,255,255,0.87)) for primary text to keep contrast comfortable.
