Blue is a primary color, meaning it cannot be created by mixing other colors. Red and yellow are also primary colors, while green is a secondary color created by mixing blue and yellow.

The RYB (Red, Yellow, Blue) color wheel is a traditional model used in art and design. It consists of three primary colors (red, yellow, and blue) and three secondary colors (green, orange, and purple) created by mixing the primaries.

Color harmony refers to the arrangement of colors in a way that creates a visually pleasing and cohesive composition. It involves selecting colors that complement each other and work well together.

Analogous color harmony involves using colors that are adjacent to each other on the color wheel. These colors share similar hues and create a harmonious and cohesive look.

Color contrast refers to the use of colors that are opposite or complementary to each other on the color wheel. This contrast creates visual interest and emphasis, making certain elements stand out in a composition.

Chiaroscuro is a lighting technique that uses a single light source to create dramatic shadows and highlights. This technique is often used to create a sense of depth and atmosphere in a scene.

In a three-point lighting setup, the key light is the main light source that illuminates the subject. It is typically placed at a 45-degree angle to the subject and slightly above eye level.

Rim lighting involves placing a light source behind the subject to create a halo effect. This technique is often used to separate the subject from the background and create a sense of depth.

Color filtering involves using colored filters on lights to create specific moods and atmospheres. These filters can be used to change the color temperature of the light, create colored shadows, or add a tint to the overall scene.

Top lighting involves placing a light source above the subject to create a dramatic overhead effect. This technique is often used to create a sense of mystery or suspense.

Color temperature refers to the overall color cast of a scene or image. It is measured in degrees Kelvin (K) and ranges from warm colors (low Kelvin values) to cool colors (high Kelvin values).

A color temperature of 3200K is typically associated with warm, inviting atmospheres. This temperature is often used in indoor lighting and creates a cozy and comfortable feel.

Color grading is the process of adjusting the color and contrast of an image to achieve a desired look. This process involves manipulating various parameters such as saturation, hue, and brightness to create a specific mood or atmosphere.

Soft lighting involves using multiple light sources to create a soft, diffused look. This technique is often used to create a flattering and even illumination of the subject.

Lighting composition refers to the use of light to create a sense of depth and dimension in a scene. This involves carefully positioning and manipulating light sources to create specific effects and draw the viewer's attention to certain elements.
