Summary
| Description | Plots of the WCAG contrast-ratio threshold 7:1 between black and the RGB components of an sRGB colour in decimal (left) and hexadecimal (right) by CMG Lee. For each curve denoting the blue component, points above the curve exceed 7:1 contrast. For simplicity, all red and green combinations in the yellow region exceed 7:1 regardless of blue value. In the SVG file, tap or hover over the gridline intersection stacks to show the colour and ratio of each swatch. | |
