What's HSV color system

The HSV color system is a way of describing colors in a manner that closely matches how people perceive them. HSV stands for:

• H – Hue: The actual color (red, green, blue, yellow, etc.).
• S – Saturation: How vivid or pure the color is.
• V – Value (Brightness): How bright or dark the color appears.

Here's how each component works:

• Hue (H): Measured in degrees from 0° to 360°.

  • 0° = Red
  • 60° = Yellow
  • 120° = Green
  • 180° = Cyan
  • 240° = Blue
  • 300° = Magenta
  • 360° = Back to Red

• Saturation (S): Measured from 0% to 100%.

  • 0% = Gray (no color)
  • 100% = Fully saturated, vivid color

• Value (V): Also measured from 0% to 100%.

  • 0% = Black
  • 100% = Maximum brightness

  Example

  • HSV(0°, 100%, 100%) = Bright red
  • HSV(120°, 100%, 100%) = Bright green
  • HSV(240°, 100%, 100%) = Bright blue
  • HSV(60°, 100%, 100%) = Bright yellow
  • HSV(240°, 50%, 100%) = A lighter, less intense blue
  • HSV(240°, 100%, 50%) = A darker blue

  Why is HSV useful?

  HSV is widely used in:

  • Image editing software (such as color pickers)
  • Computer graphics
  • Machine vision and image processing
  • LED lighting control

  It is often easier to adjust a color in HSV than in RGB because you can change the color, intensity, and brightness independently. For example, if you want a darker version of the same color, you simply reduce the Value while keeping the Hue unchanged.

  HSV and HSL are related but different color models.

  Here's the difference:

  HSV	HSL
  H = Hue	H = Hue
  S = Saturation	S = Saturation (defined differently)
  V = Value (Brightness)	L = Lightness

  The key distinction is the third component:

  • HSV (Value): Measures how bright the color is. A Value of 0% is black, and 100% is the brightest version of that hue.
  • HSL (Lightness): Measures how light or dark the color is relative to both black and white.
    • 0% = Black
    • 50% = Pure color
    • 100% = White

  For example, with the hue set to red (0°):

  • HSV(0°, 100%, 100%) = Bright red
  • HSL(0°, 100%, 50%) = Bright red

  Although they can produce the same color in some cases, changing the saturation or the third component behaves differently in each model.

  So, HSV is not HSL, even though both use Hue and Saturation and are often available side by side in graphics and image-editing software.
