While blue spirulina is only the pigment of phycocyanin from blue-green algae, green spirulina is the whole species of algae manufactured into edible goods. Therefore, quite obviously, green spirulina is mostly green while blue spirulina is of striking blue color (thanks to its blue pigment!) In terms of taste, green spirulina has a stronger fishy taste, but blue spirulina has a comparatively mild taste but a more striking blue color.
