My photo contains marbles in a water container that have lights glowing from the bottom of the container.

This photo expresses the theme of investigation because the picture portrays marbles glowing in different colors. But does the water have an effect on the marbles glowing in this type of shade, or is it the marble itself that gives off this color when colors shine on it. Why are there spots of lights splattered onto the container? What could that be? Is there a deeper meaning when light hits water in certain angles or is it the marbles again that are causing these spots with their reflection?
