RGB (Red, Green, Blue) is the most widely used color model in digital art and design. It represents colors by combining different intensities of red, green, and blue light.

Blue is one of the three primary colors in the traditional color wheel. It cannot be created by mixing other colors.

Complementary colors are colors that lie opposite each other on the color wheel. Green's complementary color is red.

A gradient is a smooth transition between two or more colors. It can be linear, radial, or angular.

Value refers to the lightness or darkness of a color. It ranges from black (lowest value) to white (highest value).

Color mixing is the process of combining different colors to create new colors.

An analogous color scheme involves using colors that are adjacent to each other on the color wheel.

Color emotion refers to the overall mood or feeling conveyed by a color or color combination.

Red is often associated with warmth and energy.

Color contrast refers to the visual effect created by the simultaneous contrast of colors.

A triadic color scheme involves using three colors that are equally spaced around the color wheel.

Saturation refers to the purity or intensity of a color. It ranges from dull (low saturation) to vivid (high saturation).

Blue is often associated with coolness and tranquility.

Colorimetry is the science of color perception.

A monochromatic color scheme involves using a single color in different shades and tints.
