Oxford Blue sits in the blue family, with the hex code #002147 mapping to rgb(0, 33, 71) in RGB and hsl(212.1, 100%, 13.9%) in HSL. In OKLCH it carries 25% perceptual lightness and 0.081 chroma — a moderately saturated, dark reading that behaves well as a primary, accent or decisive colour in modern interfaces. Blue is the most globally trusted hue and dominates the world's top brand logos for a reason — it lowers heart rate, signals stability and translates across cultures with the fewest negative connotations. It is the safe default of digital products, which is also its biggest design risk.

Pure blue links on dark backgrounds frequently fail AA — consider a lighter blue (≥ 70% L in OKLCH) or an underline. Avoid pure blue on pure red: the chromatic aberration is uncomfortable for most viewers.
