RGB to HSLA
Convert RGB to HSLA. See worked examples, understand the conversion method, and check practical limits before using your result. Check the format first.
RGB to HSLA color conversion
Use RGB to HSLA 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. HSLA output uses HSL color coordinates plus opacity. HSL lightness and HSV value are different quantities, so their numbers cannot simply be copied between formats.
Worked color example
The sample rgb(51, 102, 153) corresponds to hsla(210, 50%, 40%, 1) 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. HSLA combines hue, saturation, and lightness with an alpha channel. Alpha is a separate opacity component; changing it does not recalculate the HSL coordinates.
Transparency and rounding
The source example has no explicit alpha component. An opaque destination example uses alpha 1, or FF in hexadecimal. Check the actual result rather than assuming the tool chooses that default.
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.
