Description Usage Format Author(s) Source References Examples

BowmanTCDS contains the color distance scores for quantitative scoring of the Farnsworth panel D-15 test, from Bowman KJ (1982) The Farnsworth Dichotomous test (D-15) is a short test for detecting congenital color vision deficiencies. Bowman KJ (1982) created a table based on the Commission Internationale de l'Eclairage (International Commission on Illumination, CIE) Space and Color Difference formula, CIE 1976 (L*a*b*) with perceptual distances between pairs of caps. The table is used for the calculation of the Total Color Distance Score (TCDS) which is the sum of the CIELAB space distances between colored caps.

Cap4: Distances between colored caps for the 4th cap
Cap5: Distances between colored caps for the 5th cap
Cap6: Distances between colored caps for the 6th cap
Cap7: Distances between colored caps for the 7th cap
Cap8: Distances between colored caps for the 8th cap
Cap9: Distances between colored caps for the 9th cap
Cap10: Distances between colored caps for the 10th cap
Cap11: Distances between colored caps for the 11th cap
Cap12: Distances between colored caps for the 12th cap
Cap13: Distances between colored caps for the 13th cap
Cap14: Distances between colored caps for the 14th cap
Cap15: Distances between colored caps for the 15th cap
