NCS S 0603-R60B is a very light and slightly bluish shade of gray.
NCS is widely used in design, architecture, and industry as a standard for color communication and quality control.
The NCS notation of a color consists of a letter and four digits.
The letter indicates the hue, which can be one of the six elementary colors (black, white, yellow, red, blue, or green) or a combination of two of them.
The four digits indicate the nuance of the color, which is determined by its blackness, chromaticness, and hue.
The first digit is the percentage of blackness, which ranges from 0% (no black) to 9% (almost black).
The second digit is the percentage of chromaticness, which ranges from 0% (no color) to 9% (full color).
For example, NCS S 0603-R60B means that the color has 6% blackness, 3% chromaticness, 40% resemblance to red, and 60% resemblance to blue.
This results in a very pale and desaturated color that is closer to blue than to red.
