A hand-held colorimetric device (101) suitable for use by blind or colour-blind individuals to determine the colour of a surface-under-test (SUT), for example of a fabric, has an aperture (110) which, in use, is covered by the SUT (113) whose colour is to be determined. Six LEDs (115A, 115B, 116B, 117A and 117B) arranged in pairs (115A/115B, 116A/116 B, 117a/117B) emitting red/orange, green, and blue light illuminate the SUT and diffuse reflections therefrom containing red/orange, green, and blue spectrum sample values are used to determine the luminous reflectivity and chromaticity values for the colour of the SUT. The measured values are compared with colorimetric values of reference surfaces to determine the colour of the SUT. The colorimetric device may output the name of the colour aurally.
