Color of the dye determines which wavelengths of light that are filtered or absorbed. Type of penetrating wavelengths will stimulate specific "types" of photosynthesis required by different species of algae. It is pretty complex due to all the different species of algae. They are definitely not all the same and usually some species are unique and capable of inhabiting all sorts of conditions on earth. There are algae that live in hot springs, snow banks of far northern areas and a form that lives as co-habitants as lichens on trees, even aerophylic algae.
