The phycobilins are especially efficient at absorbing red, orange, yellow, and green light, wavelengths that are not well absorbed by chlorophyll a. [2] Organisms growing in shallow waters tend to contain phycobilins that can capture yellow/red light, [ 3 ] while those at greater depth often contain more of the phycobilins that can capture ...

The first study to incite popular skepticism of EnChroma [16] [17] [18] was a 2018 study published in Optics Express, where 48 [b] colorblind subjects performed the Ishihara test, FM-100 test and a color naming test with and without EnChroma indoor lenses.
The spectral property of phycobiliproteins are mainly dictated by their prosthetic groups, which are linear tetrapyrroles known as phycobilins including phycocyanobilin, phycoerythrobilin, phycourobilin and phycobiliviolin. The spectral properties of a given phycobilin are influenced by its protein environment.
Color analysis can be conducted by-eye, usually matching specimen color with reference charts. This methodology has been used extensively in soil analysis, often using the Munsell color system as the reference. [1] [2] While this is a traditionally used method, it is considerably subjective, relying on the ability of the naked eye to match colors.
Color correcting lenses have also been used as an aid in alleviating Dyslexia, a disorder hindering a subject's ability to read. In 2001, the company that made Chromagen lenses for color vision deficiency also claimed that the same lenses led to an "enhancement of reading rate in patients with reading disorders related to distortion of text."
