    This is off the top of my head. Please let me know what I've missed.

    Albino: Lacking pigment.

    Amelanistic: lacking melanin (black pigment).

    Aposematic: Warning coloration.

    Chromophores: Cells responsible for holding pigment.
    Xanthophores: produce yellow pigment.
    Erythrophores: produce red pigment.
    Melanophores: produce black pigment (melanin).
    Iridophores: Hold no color pigment but, hold highly reflective non-motile purine crystals that yield silver irridescent reflections.
    Leucophores: Hold no color pigment. Motile purine crystals produce white pigment.
    Cyanophores: produce blue pigment.

    Erythristic: Predominantly red morph.

    Flavistic: Sepia-toned background color.

    Leucistic: lacking or mostly lacking chromatophores. Not a true albino (ie: colored eyes).

    Melanistic: dark or near black (some markings can still be visible).

    Piebald: Having patches of white.

    Polymorphic: Having a natural variation within a single species. (eg: blue motoro ray is a polymorph of the standard non-blue motoro ray)

    Tyrosinase-Negative Albinism: An albino whose cells lack tyrosinase (enzyme that synthesizes melanin) yielding a pale-white to creamy animal with pink eyes.

    Tyrosinase-Positive Albinism: Synthesizes tyrosinase but, not melanin yielding a fawn or lavender (platinum) color.

    Xanthic: Predominantly yellow color morph.

    Correct please if I'm rong but isn't the term "Lupino" the same as the aforementioned? For example an allmost Albino Oscar but with black eyes nsted of red (where for the lack of pigment you can see the retina)

    Lupino is a trade-term and not an actual coloration-related word in the english dictionary.
