The correct choice is monochromatic colors because this color scheme involves variations of a single hue, including different shades and tints. In a monochromatic color ramp, the range is created by modifying the lightness and saturation of a base color. This means that the ramp will display a seamless transition between lighter and darker versions of that color, which helps to convey depth or intensity within a dataset effectively.

In contrast, graduated colors typically involve a range of multiple colors to represent a variable, rather than variations of a single color. Complementary colors refer to pairs of colors that are opposite each other on the color wheel, offering high contrast when used together. Analogous colors consist of colors that are next to each other on the color wheel, which create harmonies based on the combination of hues, but do not involve the singular focus of one color that is characteristic of monochromatic schemes.
