NCS S 3040-B30G (Dark Cyan) is an NCS color with a HEX approximation of #008B8B, RGB 0, 139, 139, and CMYK 100/0/0/45. It has 30% blackness and 40% chromaticness with hue B30G. Its closest Pantone Solid Coated match is 6139 C (Delta E 2.30), and its closest NCS neighbor is S 3040-B20G (Teal).
About NCS S 3040-B30G
NCS S 3040-B30G 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) · 30% blackness · 40% chromaticness · hue B30G.
Like every NCS code, S 3040-B30G is defined by a physical paint swatch in the NCS Color Atlas, not by a digital value. The HEX approximation #008B8B 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 3040-B30G is 6139 C (#008587), with a perceptual difference of Delta E 2000 = 2.30. This is a very close match suitable for most print reproduction needs.
Closest NCS neighbors
These NCS codes are perceptually closest to S 3040-B30G, sorted by Delta E 2000. Codes within the same family differ by Delta E 2-8 typically - siblings rather than duplicates.
Where NCS S 3040-B30G is used
NCS S 3040-B30G is typically specified in marine and coastal architecture, swimming pool surrounds, and modern industrial finishes. Its teal tone makes it appropriate wherever a technical, industrial, or nature-referencing palette is wanted. Before specifying NCS S 3040-B30G 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 3040-B30G in HEX?
NCS S 3040-B30G (Dark Cyan) has a HEX approximation of #008B8B. 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; #008B8B is close to every commonly-cited reference.
What does NCS S 3040-B30G mean?
The code breaks down as: S (Standard), 30% blackness, 40% chromaticness, hue B30G. 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 B30G 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 3040-B30G?
The closest Pantone Solid Coated match to NCS S 3040-B30G is 6139 C (#008587), with a perceptual difference of Delta E 2000 = 2.30. This is a very close match and is likely suitable for print reproduction.
What NCS color is closest to NCS S 3040-B30G?
