Rose as a colour name derives directly from the flower — one of the most culturally loaded plants in human history. As a pigment colour, it became standardised in the 20th century with the development of quinacridone pigments (1950s), which provided the first truly lightfast rose-pink.

Tender, romantic, and vulnerable. Rose is the softest expression of red — all its passion filtered through gentleness. Associated with love, beauty, and the ephemeral. In its deeper shades it becomes sophisticated; in its palest tints, innocent.

The rose has been the primary symbol of love in Western culture since antiquity. Picasso's "Rose Period" (1904–1906) represented his emergence from depression into human warmth. "Sub rosa" (under the rose) was a Roman phrase for secrecy. The War of the Roses in England used white and red roses as faction symbols.
