Technical Background
Converting Facebook Blue (#1877F2) to Tailwind CSS requires more than just picking the nearest hex. Our algorithm uses CIEDE2000, a perceptual color difference formula that accounts for how human vision processes lightness, chroma, and hue.
The generated scale follows the Tailwind CSS v4 OKLCH standard, ensuring perfectly uniform weight across the entire spectrum. This prevents common issues like "hue shifting" where colors turn purple or grey as they get darker or lighter. You can customize this further in our Palette Generator.
