RGB to HSL
Convert RGB to HSL. See worked examples, understand the conversion method, and check practical limits before using your result. Check the format first.
RGB to HSL color conversion
Use RGB 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
Use the red, green, and blue channel values as the starting point. Normalize the color channels by dividing by 255 when a destination formula expects values between 0 and 1. 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 rgb(51, 102, 153) 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
RGB represents red, green, and blue channels. In the 8-bit convention used by these examples, each channel runs from 0 to 255. 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
Neither example has an explicit alpha channel. This conversion changes the way color coordinates are written. If you need transparency, use an alpha-capable representation and inspect its opacity value separately.
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.
