The colour of non polar pigment was light green and its content was 4,498±0,06 mg/g (dry weight), these pigments consist of chlorophyll a (3,349±0,03 mg/g) and carotenoids (1,158±0,03 mg/g). Due to the high content of pigments from Spirulina sp, showing a bright blue colour, having functional nutrition, and non toxic, the polar pigment phycocyanin have been found suitable for use as additif natural blue colorant.
