N4: A darker than middle value Neutral Gray, precisely matched to Munsell Gray for artists exploring values.
The Neutral Grays in this line are a series of achromatic grays. Achromatic grays allow artists to adjust the value or chroma of a paint colour without altering the colour's hue. When using a Neutral Gray of the same value as the colour selected, the artist will be able to change only the chroma (intensity) of a certain colour, while maintaining the hue and value. Mixing a Neutral Gray with a colour of a different value will change both value and intensity.
The Neutral Grays follow the Munsell Value Scale, (a scale ranging from black to white), through a progression of light to dark grays. The Munsell scale defines black as N1 and white as N10. We recommend using GOLDEN Bone Black as the neutral black (equivalent to Munsell notation N1), and using Titanium White as the neutral white (N10). GOLDEN Neutral Grays include the values N2, N3, N4, N5, N6, N7, and N8. These grays are very carefully formulated to be evenly spaced and completely achromatic.
