HSLA to HSL

Converting HSLA to HSL is a trivial operation because HSLA (Hue, Saturation, Lightness, Alpha) simply extends HSL (Hue, Saturation, Lightness) by adding an alpha channel for transparency. To convert HSLA to HSL, you simply discard the alpha channel. The hue, saturation, and lightness values remain unchanged.

In essence, the process is:

1. Extract HSL Components: Take the hue, saturation, and lightness values from the HSLA color.
2. Discard Alpha: Ignore the alpha (transparency) component.

The resulting values are the HSL representation of the color. This is a lossy conversion because information about the color's transparency is lost. This conversion is useful when you need to work with a color's hue, saturation, and lightness but don't require the transparency information. It's a simple, efficient process with no complex calculations involved.
