Understanding the blacks and greys in the Winsor & Newton acrylic ranges
Mars Black is a denser, more neutral black with stronger tinting power.
Davy's Gray is a mixing grey, specially formulated for toning down a colour without the dirtying effect caused by adding black.
Graphite Grey is a dark grey which is not made from black and white. Like Davy's Gray, this makes it useful in colour mixing.
Payne's Gray is a very dark grey with a strong blue undertone that is more subtle than Ivory Black giving a purer colour when used in mixing.
Lamp Black is a blue black that is lightfast, permanent and opaque.
