What are hsb and hsl color models?

HSB (Hue, Saturation, Brightness) and HSL (Hue, Saturation, Lightness) are both color representation models. They are both alternatives to the more commonly used RGB (Red, Green, Blue) color model.

HSB:

Hue: Specifies the type of color (0 to 360 degrees, representing the color wheel).
Saturation: Intensity of the color (0% to 100%).
Brightness: Brightness of the color (0% to 100%).

HSV (Hue, Saturation, Value) is a color representation model similar to HSB (Hue, Saturation, Brightness). The terms "HSB" and "HSV" are often used interchangeably, although they can mean slightly different things depending on the context or the software you're using. In most cases, however, they represent the same color space.

HSL:

Hue: Similar to HSB, specifies the type of color (0 to 360 degrees).
Saturation: Intensity of the color (0% to 100%).
Lightness: Amount of white or black mixed with the color (0% to 100%).

Although both are similar and often confused, they are not identical. HSB tends to be more intuitive when it comes to digital art creation, as it is more aligned with how we perceive color in the real world. HSL, on the other hand, is generally easier for web and interface design, as it allows for more straightforward generation of complementary and contrasting colors.

Example in CSS:

background-color: hsl(120, 100%, 50%);

There isn't a native HSB model in CSS, but it can be emulated using available libraries or converting it to another color model like RGB or HSL.

On a web project, I would recommend sticking with HSL for CSS styling because of its direct support and wide browser compatibility. Using HSB might require you to rely on third-party libraries to convert HSB to RGB or HSL, which could have a small performance impact.

For dynamic color manipulation, you might consider using libraries like chroma-js or d3-color for more advanced color utilities. These libraries often provide methods for easily converting between color spaces, including from HSB to HSL or RGB.
