RGBA to OKLCH
Color Converter

RGBA color code, which stands for Red, Green, Blue, Alpha, is a color representation format used in digital design and computing. It is an extension of the RGB color model, where in addition to specifying the intensity of red, green, and blue (RGB) components, an alpha channel is included. The alpha channel controls the transparency or opacity of the color, with values ranging from 0 (fully transparent) to 1 (fully opaque). RGBA color codes are widely used in web design, graphic design, and image editing to define colors with varying levels of transparency, making it essential for creating visually appealing and layered digital content.

OKLCH is a color space that combines the perceptual uniformity of OKLAB with the intuitive cylindrical coordinates of LCH (Lightness, Chroma, Hue). It is increasingly becoming the preferred color space for modern web design and CSS because it allows for predictable color manipulation—such as creating harmonious palettes or adjusting lightness without shifting the perceived hue—better than HSL or standard LCH. It is natively supported in modern CSS Color Module Level 4, enabling more vibrant and accessible color schemes.
