Specifically, the regional area ratio of each color picking area in the target color picking area setting information is obtained, and the regional area ratio of each color picking area in the target color picking area setting information is determined as the regional weight coefficient of the first preset number of color picking areas. Based on the first preset number of regional weight coefficients, the regional similarity indicators of the first preset number of color picking area pairs are weighted and summed to obtain the first setting information similarity between the reference color picking area setting information of the reference user and the target color picking area setting information of the target user.
