OKLCH css

OKLCH (Oklch) is a modern color space designed for digital displays that offers several advantages over traditional color formats:

Key characteristics:

- Perceptually uniform: Changes in numeric values correspond to consistent perceived color differences, making it easier to create harmonious color schemes

- Device-independent: Colors appear consistent across different screens and devices

- Wider gamut: Can display more vibrant colors than sRGB

- Human-centric: Based on how humans actually perceive color rather than technical RGB values

Format structure:

oklch(lightness chroma hue)

- Lightness (L): 0 (black) to 1 (white)

- Chroma (C): 0 (gray) to ~0.4 (most saturated colors)

- Hue (H): 0-360 degrees around the color wheel

Why it's used in modern web design:

- Better for creating accessible color contrasts

- Easier to programmatically generate color palettes

- More predictable color manipulation (lightening, darkening, mixing)

- Native support in modern CSS (Chrome 111+, Firefox 113+, Safari 15.4+)

Your application uses oklch because it's the future-proof standard for CSS custom properties and theming systems.
