ANSWERS
=======

    1. The position of a color in the visible spectrum.

    2. The amount of hue in a color.

    3. The lightness or darkness of a color.

    4. Red, yellow, and blue.

    5. Orange, green, and purple.

    6. Colors which are neither primary nor secondary.

    7. It is based on the physical spectrum; on the 
       wavelength of the color's electromagnetic radiation

    8. It is based on how humans see colors

    9.  Physical: blending light, as in a computer or TV 
        screen
        Perceptual: blending pigments, such as paint;
        creating harmonious color themes

    10. A theme which uses only one hue, but may use
        various saturations and values, plus achromatic 
        colors.

    11. A theme which uses only hues from within three
        (or at most four) positions on the perceptual
        color wheel.

    12. A theme using only hues opposite one another on
        the perceptual color wheel.

    13. A theme using three hues: one hue, plus the two
        hues adjacent to its complement on the perceptual
        color wheel.

    14. Vary at least two aspects: hue, saturation, or
        value.

    15. Separate them with a thin strip of neutral color.

    16. Use of "color themes" such as
        primary, secondary, tertiary, monochrome,
        complementary, split complementary, and analogous;
        Understanding and using color "meanings";
        Varying saturation and value to enhance contrast;

    17. Use of warm colors as foreground, cool colors as
        background;
        Use of highly saturated colors as foreground;
        Use of high contrast areas in the image.
