'black-tinted' originates from English as a compound of 'black' and 'tinted', where 'black' comes from Old English 'blæc' meaning 'black' and 'tint' comes from Old French 'teint' (from Latin 'tingere') meaning 'to dye or color'.

'black' changed from Old English 'blæc' to Middle English 'blak' and eventually became the modern English 'black'; 'tint' derived from Latin 'tingere' to Old French 'teint' and then into Middle English as 'tint' with the past-participial/adjectival suffix '-ed' producing 'tinted', which combined with 'black' to form the compound 'black-tinted'.

Initially, 'tinted' meant 'dyed or colored' (often by deliberate application of color); over time it came to mean 'having a slight or partial coloration', so 'black-tinted' now means 'having a blackish shade' rather than necessarily being fully dyed black.
