You can anticipate how the three primary colors of light in a darkroom or theater stage will look when you shine it onto objects or pictures.

If the camera does not appear after running it, you must exit the app and restart after allowing the camera permission in the app permission.

What color would it look like if I made the space I am in a dark room and illuminated each of the three primary colors of light? If you want to try it yourself, you can make a dark room without light and check it by lighting each of the three primary colors of light. But even making a darkroom is not easy.

For example, if you shine a red light on a main character wearing yellow clothes on a play stage, what color will the main character's clothes look? Using the lighting virtual experiment app, you can simulate the desired color of light on the image reflected on the camera and check what color it will look like.

If you prepare a paper puppet show or a shadow puppet show with students during class, you will be able to check in advance what kind of light and how to light it using your smartphone without having to create a dark room and directly shine the three primary colors of light.

Since you can change the lighting color immediately while looking at the image reflected on the camera, if you use it well, you will be able to virtually express the lighting color on stage.
