A protective and decorative coating composition including about 2 to 10 different colorants which in combination with a resinous composition produce a desired visible coating. A majority of the colorants has a maximum haze of about 10% and exhibits an absorbance peak in the visible spectrum wherein at least about 50% of the total absorbance in the visible spectrum occurs at wavelengths within about 50 nm of the wavelength of the peak absorbance.
