Abstract
The hair color simulation system for simulating a dyed hair color that results from dyeing hair with a mixture of two hair color preparations includes a base screen with a first through fifth layers and an intermediate layer. The first through fifth layers and the intermediate layer are superimposed over one another so as to display a simulated hair color that is produced when the first hair line, the second hair line, the colors of the two hair color preparations and the original hair color are displayed on the layers with respective transparencies and superimposed over each other. The RGB values of the superimposed colors produced by the two hair color preparations and the original hair color are stored in data storage sections. Input sections receive choices of the two hair color preparations and a mixing ratio for the simulation.
