An interesting thing about water and light

I have been experimenting with ice and light and water in the portal I’m building for the portal framing contest. I thought I have a layer of ice underneath the water to create something like a reflection pool so you can feel like your walking on the water.
I added several emerald torches to light up the ice from below, and when I am in the water the ice is illuminated beautiful. But when you are out of the water looking in all the light and color is gone, which is unfortunate. Anyway I wish there was some way for the light to filter through the waters surface.

Here are to photos to illustrate. One under water and the other looking through the water directly at an emerald torch, but it barely being visible.
