There are unresolved issues as to the evolution of Chls vs. Organism size, via the package effect, determines the photon absorption benefit of the costs of synthesis of the pigment-protein complexes. The accessory (bacterio)chlorophylls add to the spectral range (bandwidth) of photon absorption, e.g., in algae living at depth in clear oceanic water and in algae and photosynthetic (PS) bacteria in microbial mats. Bacteriochlorophylls (BChl), absorbing in the violet/blue and near infra red (NIR), power anoxygenic photosynthesis, with one photoreaction centre and chlorophylls (Chl), absorbing in the violet/blue and red (occasionally NIR) power oxygenic photosynthesis, with two photoreaction centres. The ion pumping rhodopsins absorb blue and green photons using retinal and pump ions across cell membranes. Pigments absorbing 350-1,050 nm radiation have had an important role on the Earth for at least 3.5 billion years. University of Dundee at the James Hutton Institute, Invergowrie, Dundee, UK

Probably, but it may not be the same as Newton's.Photosynthetica 2018, 56(1):11-43 | DOI: 10.1007/s1109-x Living off the Sun: chlorophylls, bacteriochlorophylls and rhodopsins A. For example, Newton's indigo is the modern blue, while his blue corresponds to the color we refer to as cyan. In fact, there is evidence Newton's division of the spectrum doesn't even correspond to the colors we define by wavelengths. The modern spectrum typically omits indigo. So, the spectrum was first described with seven colors, but most people, even if they see color well, can't actually distinguish indigo from blue or violet. English mathematician Isaac Newton (1643–1727) coined the word spectrum (Latin for "appearance") in his 1671 book "Opticks." He divided the spectrum into seven sections-red, orange, yellow, green, blue, indigo, and violet-in keeping with the Greek sophists, to connect the colors to days of the week, musical notes, and the known objects of the solar system. If you want a number, it's around 445 nanometers, but it doesn't appear on most spectra.
There is no wavelength assigned to indigo.
