Turquoise mist where a mythic naiad might step out of a fountain.
Water Nymph is a pastel blue, close to turquoise.
It can be described as pastel, soft, light and rather unsaturated.
Set in black, because black reads best on it.
In Greek mythology, the naiads, sometimes also hydriads, are a type of female spirit, or nymph, presiding over fountains, wells, springs, streams, brooks and other bodies of fresh water. They are distinct from river gods, who embodied rivers.
Read on WikipediaWater is an inorganic compound with the chemical formula H2O. It is a transparent, tasteless, odorless, and nearly colorless chemical substance. It is the main constituent of Earth's streams, lakes, and oceans. Water is also the fluid of all known living organisms, in which it acts as a solvent. Water, being a polar molecule, undergoes strong intermolecular hydrogen bonding which is a large contributor to its physical and chemical properties. It is vital for all known forms of life, despite not providing food energy or being an organic micronutrient. Due to its presence in all organisms, its chemical stability, its worldwide abundance, and its strong polarity relative to its small molecular size, water is often referred to as the "universal solvent".
Read on WikipediaA nymph is a minor female nature deity in ancient Greek folklore. Distinct from other Greek goddesses, nymphs are generally regarded as personifications of nature; they are typically tied to a specific place, landform, or tree, and are usually depicted as maidens. Because of their association with springs, they were often seen as having healing properties; other divine powers of the nymphs included divination and shapeshifting. In spite of their divine nature, they were not immortal.
Read on WikipediaThe color of water varies with the ambient conditions in which that water is present. While relatively small quantities of water appear to be colorless and transparent, pure water has a slight blue color that becomes deeper as the thickness of the observed sample increases. The hue of water is an intrinsic property and is caused by selective absorption and scattering of blue light. Dissolved elements or suspended impurities may give water a different color.
