Understanding hue, saturation, and luminosity is essential for creating visually appealing and accessible designs. These properties help designers manipulate colors effectively for branding, UI elements, and readability.

• Hue refers to the actual color (e.g., red, blue, or green).

• Saturation defines the intensity or purity of the color—high saturation means a vivid color, while low saturation results in a more muted tone.

• Luminosity (or lightness) measures how bright or dark a color appears. It plays a key role in contrast and accessibility.

In digital design, hue, saturation, and luminosity values determine how colors interact on screens, affecting contrast, readability, and aesthetic appeal. Tools like Figma, Photoshop, and CSS allow designers to adjust hue, saturation, and luminosity for precise color control. Understanding hue, saturation, and value (HSV) or tint and luminosity helps in designing for different lighting conditions and user needs.
