We examine the colour-magnitude relation of ∼ 5000 brightest cluster galaxies (BCGs) in the Sloan Digital Sky Survey (SDSS). The colour-magnitude and colour-velocity dispersion relations of the BCGs are flatter in slope, by factors of 2 or more, than those of non-BCG early-type galaxies of similar luminosity (Mr
