Dear Mike (and Max).
I am affraid there is some confusion on the regiment here. The infomation given relates to the 4th (King's Own) Regiment of Foot which was a British regiment of line infantry, initially formed in 1680.
The King's American Regiment was an American Loyalist unit initially raised in New York from December 1776. It was commandd by Col. Edmund Fanning (PRO, AO 1/325/1287 and 1288 for pay records from 1776 to 1782; for muster rolls see Nat Arch Canada, RG8, C1902). It had distinguished services and was taken on the American Establishment as the 4th American Regiment from 7 march 1781 and the British Establishment on 25 December 1782, ordered disbanded 9 June 1783 (PRO 30/55 Vol 71), The regiment was disbanded in Canada later that year. Its uniform, according to notes in Rivington's 1783 List was 'Red Coat, Olive lapels, variety button hole' (MC&H, 1962:118). Weiderhold's Ms list (NYPL) also has red faced with blue, gold buttons for the officers. There is an engraving of Col Fanning in this uniform (Nat Arch Canada negative C46911) and, I think but would have to check further, a portrait of an officer in Fort Malden National Historic Site, Amhersburg, Ontario.
