Description

While relatively small quantities of water appear to be colorless, pure water has a slight blue color that becomes deeper as the thickness of the observed sample increases beyond 50 cm. The hue of water is an intrinsic property and is caused by selective absorption and scattering of white light. Dissolved elements or suspended impurities may give water a different color.

These reference values are based on the most accurate data available at the time and are continually updated as new measurements become available. Depending on the material and the property you're after, there's more or less variability to take into account. Use these values as a starting point, or as validation for existing materials, and then tweak further using your artistic freedom.
