Aiming at the traditional characteristics of pattern painting spot color, the shortage of manual color matching method is pointed out, and the method and approach of computer color matching based on colibri color matching software is illustrated, the color schemes pertinently are corrected，the spectral reflectance curve of the color schemes is obtained, which is basically as the same as the spectral reflectance curve of the background color, and the CIE-Lab graph is listed. By contrasting with these curves, it is shown that they have the same spectrum and colors among them, which is according with the pattern requirements in visible light wave band.
