Abstract:

To explore the feasibility of prediction of color formulas of cosmetics based on BP neural network model, one hundred lipstick samples of different proportions of pigments were prepared. The BP neural network model was constructed by MATLAB R2016a software, which was composed of two hidden layers with 15 nodes and one output layer with three network structures. The nonlinear mapping relationship between the RGB parameters and the mass ratio of lipstick pigments were formed. When the training times were 10 000 and the learning rate was 0.5, the color error parameters were all less than 0.6, and there was no significant color difference between the predicted formula and the real formula. Hence the color matching method based on BP neural network model could directly generate the color formula and provide a quick and simple reference tool for color engineers.

Key words: BP neural network, color matching, color prediction, Matlab, lipstick
