How to Use This Tool
Enter your color as rgba(r, g, b, a) — for example, rgba(255, 122, 89, 1). The alpha value ranges from 0 to 1. Enable the Alpha toggle to include transparency in the OKLCH output, producing oklch() values with a slash-separated alpha channel (e.g. oklch(72.9% 0.1696 35.11 / 0.8)). OKLCH lightness and chroma adjustments look visually consistent across all hues, making this format ideal for building accessible design systems. Click any value to copy it.
