HSLA to HSL

HSLA to HSL color conversion

Use HSLA to HSL when a design specification, stylesheet, or color editor needs a different representation of the same color. Start hexadecimal input with #, or use a lowercase rgb, rgba, hsl, hsla, or hsv function name. Select Submit, then check the target-format result before copying it.

How this conversion works

Convert the HSL coordinates through RGB using chroma (1 - |2L - 1|) × S, with S and L normalized to 0 through 1. Handle alpha separately from the color-coordinate calculation. For HSL output, normalize RGB, set lightness to (maximum + minimum) ÷ 2, and calculate saturation from the channel difference and lightness. Gray colors have no unique hue.

Worked color example

The sample hsla(210, 50%, 40%, 0.8) corresponds to hsl(210, 50%, 40%) for the color coordinates illustrated here. Small differences in the final digits can result from rounding. This example explains the mathematical representation; it does not establish which input syntax this tool accepts.

Understand the formats

HSLA combines hue, saturation, and lightness with an alpha channel. Alpha is a separate opacity component; changing it does not recalculate the HSL coordinates. HSL describes hue, saturation, and lightness. Lightness is halfway between the largest and smallest normalized RGB channels, rather than a direct measure of perceived brightness.

Transparency and rounding

The destination format shown here has no explicit alpha channel. A coordinate-only conversion cannot preserve transparency. Dropping alpha and compositing over a background are different operations; inspect the result and do not assume which operation this tool performs.

Frequently asked questions

Will the converted color look identical everywhere?

Equivalent coordinates describe the same color within the assumed color model. Displays, color profiles, surrounding colors, and backgrounds can affect appearance. Compare the result in the application where you will use it.

Can I interchange HSL lightness and HSV value?

No. They are different calculations. Recalculate the destination coordinates instead of moving the same percentages between HSL and HSV fields.
