The present invention relates to a color therapy system using visible light which provides a user with guiding information regarding to the characteristics of a disease, a therapeutic method for the disease, an irradiating method of ray and precautions, and an irradiating location of the ray on a screen. The present invention is attached to the color therapy location of the body by a double-sided tape, a hydro gel pad, an air adsorption plate and the likes on a portable smart communication apparatus (for example, a smartphone and the likes) equipped with a color therapy program controlling a color therapy operation of the color therapy device according to a signal requiring for the operation of the color therapy device selected by the user, so as to be used to intensively irradiate visible light, and perform the color light therapy by being connected with the color therapy device equipped with a light source (for example, an LED) which irradiates visible light (for example, a visible light which has irradiating ranges of 400-800 nm) for the color therapy for the body. Since the present invention uses visible light, it is safe without any side effects, and since the present invention provides a user with guiding information such as in regards to the characteristics of the disease, a therapeutic method for the disease, an irradiating method of ray and precautions and the likes; it has the advantage from a user's prospective that the user can easily treat and prevent various diseases without the inconvenience even though learning the guiding information separately, and in particular be able to treat and prevent various diseases by converting the irradiating location of the ray and the color of visible light through only one portable smart communication apparatus.
