Abstract This paper got the value of L*、a*、b* of the different concentration of transparent colored solutions by using CMOS sensor of Android smart mobile phone and Android mobile phone software Color Grab, introduced the corresponding data into Excel to get the corresponding value of chromatism, obtained the concentration of the solution by establishing the numerical relationship between value of chromatism and concentration, and measuring value of chromatism of the transparent colored solution by the smart mobile phone. After calibration, the system no longer needed standard solution.
