Color to Grayscale
Convert any color to its grayscale equivalent using the ITU-R BT.709 luminance formula (0.2126R + 0.7152G + 0.0722B). Shows visual comparison.
How to Use Color to Grayscale
The Color to Grayscale converter transforms any color into its perceptually accurate grayscale equivalent using the ITU-R BT.709 luminance formula: L = 0.2126×R + 0.7152×G + 0.0722×B. This formula weights green most heavily because human eyes are most sensitive to green light. Enter a hex color (#RGB or #RRGGBB) or rgb() value and instantly see the grayscale result with a visual side-by-side comparison. The tool outputs the grayscale value, hex code, and RGB notation. Useful for designers checking contrast, preparing images for print, and understanding color luminance.
Step-by-Step Instructions
