Abstract: Photoacoustic colorimetry (PAC) was first proposed.It is believed that the unnormalized photoacoustic spectrum can be taken directly by CIE standard colori-metric system to get the dominant wavelength (hue), purity (chroma) and lightness (value), by matching of spectral tristimulus values.Several PAC experiments of Fogra Pms control strips, dyes, color papers, soils, fluorescent and biological materials etc.were made.

Key words: photoacoustic colorimetry, CIE colorimetric system
