About NCS S 2050-G50Y
NCS S 2050-G50Y 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) · 20% blackness · 50% chromaticness · hue G50Y.
Like every NCS code, S 2050-G50Y is defined by a physical paint swatch in the NCS Color Atlas, not by a digital value. The HEX approximation #7FFF00 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 2050-G50Y is 2285 C (#93DA49), with a perceptual difference of Delta E 2000 = 9.20. The colors are noticeably different - specify NCS and Pantone separately rather than substituting.
Closest NCS neighbors
These NCS codes are perceptually closest to S 2050-G50Y, sorted by Delta E 2000. Codes within the same family differ by Delta E 2-8 typically - siblings rather than duplicates.
Where NCS S 2050-G50Y is used
NCS S 2050-G50Y 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 2050-G50Y 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 2050-G50Y in HEX?
NCS S 2050-G50Y (Chartreuse) has a HEX approximation of #7FFF00. 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; #7FFF00 is close to every commonly-cited reference.
What does NCS S 2050-G50Y mean?
The code breaks down as: S (Standard), 20% blackness, 50% chromaticness, hue G50Y. 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 G50Y 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 2050-G50Y?
The closest Pantone Solid Coated match to NCS S 2050-G50Y is 2285 C (#93DA49), with a perceptual difference of Delta E 2000 = 9.20. These are noticeably different colors - for accurate brand work, specify NCS and Pantone separately rather than substituting.
What NCS color is closest to NCS S 2050-G50Y?
The closest NCS neighbors to S 2050-G50Y are S 1050-G10Y (Bright Green, Delta E 5.1), S 2050-G (Medium Green, Delta E 16.3), S 0580-Y (Bright Yellow, Delta E 22.4). Codes within the same family typically differ by Delta E 2-8 - siblings rather than duplicates.
Where is NCS S 2050-G50Y commonly used?
NCS S 2050-G50Y is typically used 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 2050-G50Y for a production run, verify against a physical NCS color fan - the same code looks meaningfully different in different finishes.
