Description

The colors of a soap bubble are the result of an interaction between the light reflected from the front and back surfaces of the soap film, a phenomenon known as thin-film interference. The thickness of a soap bubble can range between 10 nm and 1000 nm. It's thinner at the top due to gravity.

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.
