"New York Volunteers uniform" Topic

Getting ready to paint one of my favorite loyalist units the New York Volunteers (3rd American). My army is painted/organized for 1779-1781 southern campaigns. Checked the usual sources like Philip Ketcher, Mollo and McGregor, etc. Red coats faced buff or blue is usual answer.
Then. In looking throughout Leferts I noticed a return from the Carleton papers. In 1780 New York volunteers green coats, waistcoat and breeches white, sergeants laced hats.
is this a typo on the date? Or is there evidence of some loyalist units still wearing green later in the war? I interested if anyone has come across period inspection returns on this. Thank you!

The NYV had a complicated history, and the number of companies varied throughout the war. Looking at the various sources, I suspect red coats faced blue was the norm for most of the war, including service in the South (they included a mounted infantry company under Major Coffin, from Septemer 1780 to their return to NYC in 1782). Red coats faced buff are recorded at the end of the war.

The green uniform is not a mistake, but is a distinct unit – Captain Althaus's company of riflemen, which was originally part of Emmerich's Chasseurs, but joined the NYV in 1779 (possibly earlier). It was eventually transferred to the Queen's Rangers; I'm not sure when exactly, but the company was still part of the NYV when they fought alongside the QRs at Spencer's Ordinary in June 1781.

As an aside, in December 1779, Althaus's company was with that part of the British fleet carrying troops from NYC to the siege of Charleston that was hit by a storm and forced to "ride" it all the way to Ireland and England, from where they did not return until the Spring of 1780.

Thank you very much for the help!
