An albino discus typically has a pale or white body color with a lack of pigmentation. The eyes are often red or pink due to the absence of melanin. Albino discus may display a subtle iridescence on their scales. Cobalt discus, on the other hand, are known for their intense cobalt blue coloration. The entire body can have a vivid blue hue, making them quite striking in aquariums. The intensity of the blue color may vary among individual fish. When these two traits combine together, incomplete dominance is exhibited, and the result is a pale iridescent fish with a beautiful variegated pattern.
