Origin of Crimson and Scarlet

Crimson

Crimson takes its name from the Old Spanish 'cremesin', which came from Arabic 'qirmiz' — the Kermes scale insect used to produce the dye in the Mediterranean from antiquity through the Renaissance. Crimson was the color of Byzantine imperial documents and medieval cardinal robes before cochineal displaced it.

Scarlet

Scarlet as a word originally described a luxurious woolen cloth (not a color) imported through the Middle East in the 12th century. Because the cloth was usually dyed with kermes and later cochineal in bright red, the word gradually transferred from fabric to hue by the late Middle Ages.

PickCrimson

Crimson hits a 4.99:1 WCAG contrast against white — safer for text-heavy interfaces — where Scarlet only reaches 3.82:1 and risks failing AA at small body sizes.

Scarlet is a warm tone that flatters spring/summer collections and warmer skin undertones, while Crimson leans warmer and is better suited to autumn/winter layering.

▣Interior design & walls
PickCrimson

Crimson is the more muted of the two (83% saturation) and sits more calmly on large wall surfaces, while Scarlet's higher chroma can overwhelm a room when used beyond accent pieces.
