Different values of Manganese Blue Hue and Carmine watercolours are created using three different greys. Davy’s Grey is a slate pigment named after Cotman’s student Henry Davy. It is a transparent grey with a greenish tinge. Payne’s Grey was named after painter and printmaker William Payne, it was first recorded in 1835 and is a dark blue-grey that is more subtle than black, making it is great for creating tones. Finally, Neutral Tint, a soft grey tone created in 18th century England that also allowed artists to avoid using black, which could corrupt the quality of other colours. All the greys are demonstrated here to show the effects they have on other colours.
