Question 1

What is hue, saturation, and Luminance (HSL)?

Accepted Answer

Hue, saturation, and luminance (HSL) is a color model used to define and adjust colors in digital and visual applications. Hue represents the actual color, such as red, blue, or green, and is measured in degrees from 0 to 360 on a color wheel. Saturation determines the intensity or purity of a color. Fully saturated colors appear vivid, while lower saturation makes them more muted or grayish. Luminance, also known as brightness, represents how light or dark a color is, affecting its overall visibility.

Question 2

How does saturation affect color perception?

Accepted Answer

Saturation influences how vibrant or dull a color appears. Higher saturation makes colors look more vivid and intense, while lower saturation reduces their intensity, making them appear faded or closer to grayscale. Adjusting saturation can drastically change an image’s mood. For example, desaturated colors create a nostalgic or cinematic feel, while high saturation makes visuals pop with energy.

Question 3

What is the difference between hue and color?

Accepted Answer

Hue is a specific aspect of color that refers to its position on the color spectrum, such as red, green, or blue. Color, on the other hand, is a broader term that includes not only hue but also saturation and brightness (or luminance). For example, pink and maroon share the same hue, which is red, but differ in saturation and brightness.

Question 4

How do you change the hue of a picture?

Accepted Answer

To change the hue of a picture, you can use image editing software like Photoshop, Lightroom, or DaVinci Resolve. These programs provide HSL (Hue, Saturation, and Luminance) sliders to adjust color tones selectively.
