About NCS S 3055-R50B
NCS S 3055-R50B 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 · 55% chromaticness · hue R50B.
Like every NCS code, S 3055-R50B is defined by a physical paint swatch in the NCS Color Atlas, not by a digital value. The HEX approximation #8B008B 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

Where NCS S 3055-R50B is used
NCS S 3055-R50B is typically specified in specialty architectural accents, automotive finishes, and decorative industrial elements. Its purple tone makes it appropriate wherever a refined, specialty, or decorative palette is wanted. Before specifying NCS S 3055-R50B 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 3055-R50B in HEX?
NCS S 3055-R50B (Dark Magenta) has a HEX approximation of #8B008B. 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; #8B008B is close to every commonly-cited reference.
What does NCS S 3055-R50B mean?
The code breaks down as: S (Standard), 30% blackness, 55% chromaticness, hue R50B. 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 R50B 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 3055-R50B?
The closest Pantone Solid Coated match to NCS S 3055-R50B is 2070 C (#8F1A95), with a perceptual difference of Delta E 2000 = 2.58. This is a very close match and is likely suitable for print reproduction.
What NCS color is closest to NCS S 3055-R50B?
