The invention provides a color temperature compensation method applied to a display panel and a display device. According to the color temperature compensation method, full-gray-scale color temperature data is determined through first chromaticity coordinate information, compensation color temperature data is determined through second chromaticity coordinate information, the full-gray-scale color temperature data and the compensation color temperature data which are not corrected can be matched, and the difference value between each piece of gray-scale color temperature data and standard gray-scale color temperature data which are not corrected is determined; if the color temperature data is not corrected, adjusting the gray scale of each pure color picture so as to change the compensation color temperature data, enabling the compensation color temperature data to be similar to or even equal to the standard gray scale color temperature data, and determining the compensation color temperature data correspondin
