Visual perception
- At HSL(0, 74%, 49%), Maximum Red has a relative luminance of about 0.16 on a 0-1 scale, which can make it harder to distinguish for people with red-green color blindness if used alongside similarly saturated greens or reds; pair it with a distinct lightness or add non-color cues such as icons or labels.
Technology specific
- Maximum Red (#D92121) renders consistently on standard sRGB displays; on wider-gamut or uncalibrated screens, expect minor shifts in perceived saturation. For print reproduction, convert from RGB to CMYK and proof physically, since highly saturated colors like this can shift noticeably between screen and print.
Guidance
Use Maximum Red with white text for readability (contrast ratio approximately 5.0:1). Reserve it for smaller accent areas rather than large backgrounds since high saturation can overwhelm at scale.
