NCS S 2500-N - Darker Grey
NCS S 2500-N (Darker Grey) is an NCS color with a HEX approximation of #B9B9B9, RGB 185, 185, 185, and CMYK 0/0/0/27. It has 25% blackness and 0% chromaticness with hue N. Its closest Pantone Solid Coated match is Cool Gray 4 C (Delta E 0.91), and its closest NCS neighbor is S 3000-N (Charcoal Grey).
About NCS S 2500-N
NCS S 2500-N is part of the Natural Color System, a perceptual color notation system developed in Sweden and widely used across Scandinavia and Northern Europe for architectural paint specifications. The code reads as: S (Standard) · 25% blackness · 0% chromaticness · hue N.
Like every NCS code, S 2500-N is defined by a physical paint swatch in the NCS Color Atlas, not by a digital value. The HEX approximation #B9B9B9 is the most commonly-published translation, but physical NCS swatches are the only authoritative source. The full NCS Atlas contains roughly 1,950 codes; our reference covers 50 benchmark codes.
Closest Pantone match
The closest Pantone Solid Coated color to NCS S 2500-N is Cool Gray 4 C (#BBBCBC), with a perceptual difference of Delta E 2000 = 0.91. This is a very close match suitable for most print reproduction needs.
Closest NCS neighbors
These NCS codes are perceptually closest to S 2500-N, sorted by Delta E 2000. Codes within the same family differ by Delta E 2-8 typically - siblings rather than duplicates.
Where NCS S 2500-N is used
NCS S 2500-N is typically specified in architectural facades, metal cladding, concrete surfaces, infrastructure, and modern interiors. Its gray tone makes it appropriate wherever a neutral, architectural, or structural palette is wanted. Before specifying NCS S 2500-N for a production run, verify the color against a physical NCS color fan under the actual lighting conditions and finish (matte, semi-gloss, gloss) that will be used - the same code looks meaningfully different across finishes.
Frequently asked questions
What is NCS S 2500-N in HEX?
NCS S 2500-N (Darker Grey) has a HEX approximation of #B9B9B9. This is the widely-published mid-range value - NCS is a perceptual color notation system, not a digital one, so any HEX representation is a translation rather than a definition. Different published sources disagree by 2-5% for the same NCS code; #B9B9B9 is close to every commonly-cited reference.
What does NCS S 2500-N mean?
The code breaks down as: S (Standard), 25% blackness, 0% chromaticness, hue N. Blackness measures how much black the color contains relative to pure white (0%) and pure black (100%). Chromaticness measures how saturated the color is relative to a neutral gray at the same blackness. Hue N specifies the position on the NCS perceptual color wheel - with Y for yellow, R for red, B for blue, G for green, or N for neutral.
What Pantone color is closest to NCS S 2500-N?
The closest Pantone Solid Coated match to NCS S 2500-N is Cool Gray 4 C (#BBBCBC), with a perceptual difference of Delta E 2000 = 0.91. This is a very close match and is likely suitable for print reproduction.
What NCS color is closest to NCS S 2500-N?
The closest NCS neighbors to S 2500-N are S 3000-N (Charcoal Grey, Delta E 3.6), S 2000-N (Medium Grey, Delta E 3.6), S 1500-N (Grey, Delta E 7.0). Codes within the same family typically differ by Delta E 2-8 - siblings rather than duplicates.
Where is NCS S 2500-N commonly used?
NCS S 2500-N is typically used in architectural facades, metal cladding, concrete surfaces, infrastructure, and modern interiors. Its gray tone makes it appropriate wherever a neutral, architectural, or structural palette is wanted. Before specifying NCS S 2500-N for a production run, verify against a physical NCS color fan - the same code looks meaningfully different in different finishes.
