Here are several photos of our pool, which is Tahoe blue pebbletec with luminous glass beads added (in jade mix). The beads do not really alter the water color, but they enhance the pebble finish and sparkle a bit.
The color changes a lot depending on the lighting. It is evenly blue/green, but in bright sun, it is bright aqua, which is most the time. In the evenings it appears quite dark and sometimes it looks almost royal blue. When swimming, it looks very similar to tropical Caribbean water like you might see when snorkeling. The color is intense.
We chose it because we like dark finishes, but also like color, so this seemed like a good compromise. Also, we have colored LED lights and Tahoe blue is about as dark as one can go and still have the colored lights show up well.
