<p>A coloured coating composition comprising a white base paint and at least one coloured pigment in a form that can be readily mixed with the white base paint, the white base paint comprising a film-forming polymer, a liquid carrier, one or more opacifying white pigments and one or more extenders, the coloured coating composition having a light reflectance value Y less than 110, and greater than that defined by the equation Y = mC + K, where 25 > C > 1.0, C being the chroma of the coloured coating composition, m and K being empirical coefficients selected according to the type and number of the type of the at least one coloured pigment, and dependant on the hue angle of the coating composition (Figure 1).</p> |
