Note about Conversion Accuracy
The CMYK to NCS conversion is an approximation. NCS is a perceptual color system based on how humans see color, while CMYK is a color model for printing. The conversion finds the closest NCS match to your CMYK values.
Understanding Color Systems
CMYK Color Model
CMYK is a subtractive color model used in color printing:
- C (Cyan): Ranges from 0-100%
- M (Magenta): Ranges from 0-100%
- Y (Yellow): Ranges from 0-100%
- K (Key/Black): Ranges from 0-100%
CMYK is primarily used in printing processes, where inks subtract brightness from white paper.
NCS Color System
The Natural Color System (NCS) is based on how humans perceive color:
- Uses six elementary colors: white (W), black (S), yellow (Y), red (R), blue (B), and green (G)
- NCS notation (e.g., "S 1050-R90B") includes:
- S: Indicates the current version of the NCS standard
- 1050: The nuance (10% blackness, 50% chromaticness)
- R90B: The hue (Red with 90% Blue)
NCS is widely used in architecture, design, and color specification where perceptual accuracy is important.
