The combination that creates a neutral tone is complementary colors. Complementary colors are located directly opposite each other on the color wheel. When these colors are mixed together in equal proportions, they effectively offset each other's vibrancy. This mixing process usually results in a neutral tone, such as gray or brown, depending on the specific colors involved. The neutralization occurs because the opposing hues cancel each other out, leading to a reduction in saturation and brightness, which is characteristic of neutral tones.

In contrast, primary colors consist of red, blue, and yellow, which are the foundational colors that cannot be created by mixing other colors. While they can produce a wide array of hues when mixed, they do not inherently create neutrality.

Analogous colors, which are colors that sit next to each other on the color wheel, typically create harmony within a particular color family but do not produce neutral tones as they maintain vibrancy.

Monochromatic colors utilize different shades, tints, and tones of a single hue, leading to variations in lightness and saturation rather than achieving neutralization.

Thus, the correct choice focuses on the inherent characteristics of complementary colors, leading to the creation of neutral tones through their interaction.
