chromametric assessment of the colour of the lesion was performed using a Minolta CR 300 Chroma Meter (Osaka, Japan). 4 The chromameter was set in the L*a*b* colour space. The equation C* = [a* + b*]/ describes the quality of colour. L* represents the 'value' of the colour, and in comparisons, positive values indicate lighter and negative darker colours. The equation E* = [L* + a* + b*]/ takes into consideration both the quality (C*) and the value (L*) of colour and allows an overall comparison of colours. Measurements of skin lesions at different time points were made comparable by concomitant evaluation of normal skin of the same anatomical site. 5
