Color: Luminosity in HSL

We explored the HSL color model broadly previously — now we will look at Luminosity, one of its three properties. So what is Luminosity? Luminosity is the value that spans from pure black (darkest) to pure white (lightest). Now how does Luminosity influence any color? If we change the Luminosity values to 0 (zero) for a given colors, it does not matter what Hue or Saturation values they have – they will all be black! This reasoning is easy to explain using an analogy. In a very dark room, if you switch off the light you will be left with pitch darkness, and any object of any color will appear black. That’s precisely what’s happening here too!

Explore how Luminosity works within the HSL color model.
