This work examines sensory and instrumental methods for quantifying color of fabrics and
investigates the relationship between fabric color and UV transmittance. The color of 175
samples was visually categorized by human judges into color groupings and measured
instrumentally according to the CIE XYZ and CIE LAB systems using a spectrocolorimeter.
The relationship between color and UVA, UVB and UVR transmittance was examined and
the most appropriate method for describing the relationship between UV protection and color
was determined. Color depth rather than color per se affected mean UV transmittance with
dark fabrics confirmed as being most effective. L* (lightness), Y (brightness), were found to
be equally effective descriptions of the `color'/transmittance relationship. Manufacturers
seeking to color fabrics so as to minimize UV transmittance should select colors with CIE
L* of approximately < 38 or CIE Y of approximately < 28. Medium and high transmittance
levels were less clearly related to CIE values.
