What You'll Learn
RGB values
The RGB values for Glidden 00NN37/000 Granite Grey are 158, 158, 157.
RGB stands for Red, Green, and Blue. It is a colour model that uses additive colour mixing to create an array of colour shades. RGB is used in digital design, and by combining red, green, and blue light in varying intensities, designers create the colours we see on screens. Each colour channel has an intensity ranging from zero (complete darkness) to 255 (maximum brightness). When all three colours are mixed at their lowest intensity, they create black.
RGB colours are used for on-screen viewing. Some common applications that use the RGB colour model include web design, graphic design, digital displays, digital photography, and video editing. RGB and CMYK are the two main colour models used for designs. CMYK colours are used for colour printing.
The RGB values for Glidden 00NN37/000 Granite Grey are 158, 158, and 157. These values are close to each other, which means the corresponding colour is close to neutral. The higher the RGB values, the lighter the colour, and the lower the RGBs, the darker the colour.

Light reflectance value (LRV)
LRV is frequently used by design professionals, such as architectural colour consultants, architects, environmental graphic designers, and interior designers. It is often reported on paint chips or paint samples. Designers use LRV to determine the number and type of light fixtures needed to provide proper lighting for interior spaces. For example, in a dark room, a dark colour won't reflect light as it doesn't receive any light, and it has a low LRV.
LRV can also be used to determine the amount of contrast between colours. The British Standards Institute's guidance recommends that adequate visual contrast is provided if the LRV of the contrasting areas differs by at least thirty points.
The LRV for Glidden 00NN37/000 Granite Grey is 34.15. This means that the paint will reflect some light, but it will be on the darker side, absorbing more light than it reflects.

Hue angle
The Glidden 00NN37/000 Granite Grey has a hue angle of 110.56.
In painting, a hue is a pure pigment, without tint or shade (added white or black pigment, respectively). The human brain processes hues in areas in the extended V4 called globs. The concept of a colour system with a hue was first explored in 1830 by Philipp Otto Runge's colour sphere. The Munsell colour system from the 1930s was a great step forward, as it was realised that perceptual uniformity means the colour space can no longer be a sphere.
The hue angle is computed using a formula that determines the ordering of R, G, and B values. The formula is:
> {\displaystyle {\frac {M-L}{H-L}}}
Where H is the highest of R, G, and B; L is the lowest, and M is the middle one between the other two.

Chroma
When considering chroma, it is also important to understand hue angle, which represents the position of a colour's hue around a colour wheel. The hue angle for 00NN37/000 Granite Grey is 110.56, indicating a cool-toned grey with a slight blue or green influence.
The combination of a low chroma and a hue angle in the range of 110-120 degrees suggests that 00NN37/000 Granite Grey is a soft, cool-toned grey with a subtle, muted appearance. This makes it a versatile colour that can be used in a variety of interior and exterior applications, providing a neutral backdrop that complements a range of design styles and colour palettes.
It is worth noting that chroma is just one aspect of a colour's appearance, and other factors such as lighting conditions, surrounding colours, and surface texture can also influence how a colour is perceived. Therefore, while the chroma of 00NN37/000 Granite Grey may suggest a soft and subtle grey, the final appearance will depend on the specific context and lighting conditions in which it is used.
