About NCS S 3050-G20Y
NCS S 3050-G20Y 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 · 50% chromaticness · hue G20Y.
Like every NCS code, S 3050-G20Y is defined by a physical paint swatch in the NCS Color Atlas, not by a digital value. The HEX approximation #228B22 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 3050-G20Y is 2426 C (#008C15), with a perceptual difference of Delta E 2000 = 1.50. This is a very close match suitable for most print reproduction needs.
Closest NCS neighbors
These NCS codes are perceptually closest to S 3050-G20Y, sorted by Delta E 2000. Codes within the same family differ by Delta E 2-8 typically - siblings rather than duplicates.
Where NCS S 3050-G20Y is used
NCS S 3050-G20Y is typically specified in architectural facades, outdoor infrastructure, park and landscape elements, and safety signage. Its green tone makes it appropriate wherever a technical, industrial, or nature-referencing palette is wanted. Before specifying NCS S 3050-G20Y 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 3050-G20Y in HEX?
NCS S 3050-G20Y (Forest Green) has a HEX approximation of #228B22. 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; #228B22 is close to every commonly-cited reference.
What does NCS S 3050-G20Y mean?
The code breaks down as: S (Standard), 30% blackness, 50% chromaticness, hue G20Y. 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 G20Y 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 3050-G20Y?
The closest Pantone Solid Coated match to NCS S 3050-G20Y is 2426 C (#008C15), with a perceptual difference of Delta E 2000 = 1.50. This is a very close match and is likely suitable for print reproduction.
What NCS color is closest to NCS S 3050-G20Y?
