Description	Presented is a simple non-destructive method for quantifying conodont colour based on digital processing of conodont images taken by a digital camera attached to a binocular microscope operating under incident light, using the RGB colour space. The digital colour data was calibrated to a spectral reflectance of the standard colour background. The results from the Moravo-Silesian Zone (MSZ) of the Bohemian Massif, Czech Republic, demonstrate an excellent relationship existing between the digital intensities of the red (R), green (G) and blue (B) colours and CAI in the range from CAI 3 to CAI 6. The R/B colour ratio proved the best proxy of CAI. The R/B ratio decreases with increasing CAI from values of about 1.6 (CAI3) to about 1.0 (CAI5) and then slightly increases to 1.15 (mean for CAI 5.5) and 1.26 (mean for CAI6). It is closely related to CAI (R2 = 0.8974) within CAI 3 to CAI 5 interval.
