How do the blacks and greys differ in Professional Acrylic?

This guide compares different blacks and greys in Winsor & Newton's Professional Acrylic range: Ivory Black for general use, Mars Black for stronger tinting, Davy’s Gray and Graphite Grey for color mixing without muddiness, Payne’s Grey for subtle blue undertones, and Lamp Black for lightfastness and opacity.

• Ivory Black is a brown black of moderate tinting strength, recommended for general use.
• 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 that is not made from black and white. As with Davy’s Gray, this makes it useful in colour mixing.
• Payne’s Grey is a very dark grey with a strong blue undertone. It 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.
