There are patterns in the color combinations that make people feel good. However, it is difficult to use the optimum color scheme without knowledge and experience. If the furniture does not fit the room, such as when you move, it is difficult to replace or reselect the interior, so you must choose the interior carefully. Therefore, we created a system that enables color learning using simulation of the color scheme and arrangement of furniture in the room and judgment of color harmony. The color harmony is judged using the colors arranged in the room. By using this system, the arrangement of furniture can be decided in advance, and the color scheme that suits the room can be learned. As a result of conducting an evaluation experiment of this system, it was highly evaluated in terms of practicality and learning effect.
