chlorophylls and carotenoids are found in plastids (chloroplasts and chromoplasts). Specifically, the text describes carotenoids (which include xanthophylls) as 'fat soluble' pigments . In contrast, anthocyanins are listed as secondary metabolites . Unlike the fat-soluble pigments found in plastids, anthocyanins are water-soluble pigments typically stored in the vacuole (sap).
