the word 'tint' entered english in the early 18th century, borrowed from the latin 'tinctus', the past participle of 'tingere', meaning 'to dye, dip, or moisten'. this latin root is the source of several english colour-related words, such as 'tinge' and 'tincture'. the core semantic logic evolved from the physical act of dipping something into a dye to impart colour, to the more abstract and delicate notion of a slight shade or variation of a colour. thus, the modern meaning retains the original sense of applying colour but with a connotation of subtlety rather than full saturation.

this word is a simplex form. it is derived from the latin verb 'tingere' (to dye, to moisten), which itself is of obscure origin, possibly from a proto-indo-european root meaning 'to wet' or 'to soak'.
