RGB to CMYK Converter
Instantly convert RGB color values to CMYK and vice versa.
Conversion Formula:
RGB to CMYK:
C = (1 - R/255 - K) / (1 - K)
M = (1 - G/255 - K) / (1 - K)
Y = (1 - B/255 - K) / (1 - K)
K = 1 - max(R/255, G/255, B/255)
CMYK to RGB:
R = 255 × (1-C) × (1-K)
G = 255 × (1-M) × (1-K)
B = 255 × (1-Y) × (1-K)
