Is there a benefit to water exposed to sunlight in different colored glass? What color is preferred? Or putting quartz crystals in the water exposed to sunlight? Does that improve its health benefits or help to restore the life beings in the water?

Light itself has beneficial effects on water. The best source of glass to use for sun exposure of water would be either clear or in the blue tint range because that is more like the wavelength of visible light reflected from the sky and its atmospheric makeup. So natural daylight, being in the blueish range, is the most natural. So clear glass is just fine. The idea of using blue containers is more for eye appeal than for practical benefit. It is inherently more water-like, and the idea of a darker blue representing depth and substance, creates a kind of feeling about a container of water with tinted glass of this kind—it looks more rich, and full, and complete, and appears intuitively to be a safe and healthy color because it corresponds to natural settings, when looking at water in depth, which takes on this spectral hue, but that is an impression more so than an actuality of the physics here. Something that interferes in a minimal way with delivery of light would be highest and best if one wants to imbue the positive effects of the sun’s energy on water. It will have benefits as the energy conveyed to the water will persist and will be delivered to the body as well. It is a way of getting the benefits of sunlight indirectly although not the most efficient or least expensive for most situations.
