Does brown algae(fucoxanthin pigment) really absorb a greater part? Most chlorophyll has a gap in the green spectrum. https://www.mdpi.com/remotesensing/remotes

  The chlorophylls always have a gap in the green or in the blue-green, where the light is reflected. However, in the non-green algae there are various accessory pigments, which absorb light in bands not used by chlorophyll and which transfer the generated photoelectrons to chlorophyll, enhancing the amount of the light whose energy is captured. The ancestors of the green algae, which adapted to a terrestrial freshwater environment, then to the dry land, becoming land plants, have lost most accessory pigments, because they now received more light than they could use.
