About this color

Red sits at 0° on the color wheel with 100% saturation and 50% lightness, placing it in the red segment of the spectrum. With saturation at 100%, this is a high-chroma color: the kind that anchors palettes and demands considered placement. Its mid-range lightness positions it as a mid-tone: neither a background color nor a deep accent, but something in between.

In digital environments, Red is rendered as rgb(255, 0, 0), where the red channel dominates at 255, creating a strongly red-skewed appearance. The mid-range lightness and strong saturation make this versatile for both foreground and background roles, depending on what it is paired against.

For print, Red translates to a CMYK breakdown of 0C 100M 100Y 0K. With almost no black ink (0%), this color is built almost entirely from process inks: 100% magenta, 100% yellow. This profile tends toward vibrancy in print, though ink density limits on press may affect saturation on coated versus uncoated stock. In brand applications, this exact value is specified as YouTube Red.
