Exemplos

Convert a Figma HEX color to HSL for CSS

Translate a design tool HEX value to HSL for use in CSS custom properties.

Entrada

#3B82F6

Saída

RGB: rgb(59, 130, 246) | HSL: hsl(217, 91%, 60%) | HSLA: hsla(217, 91%, 60%, 1)

Add transparency to an RGB color

Get the RGBA equivalent of a solid color with 50% opacity for a semi-transparent overlay.

Entrada

rgb(0, 0, 0) with alpha 0.5

Saída

RGBA: rgba(0, 0, 0, 0.5) | HEX with alpha: #00000080

Casos de uso comuns

  • Translating HEX colors from design tools (Figma, Sketch) into CSS RGB or HSL values
  • Converting solid colors to RGBA for semi-transparent overlays and backgrounds
  • Using HSL values for programmatic lightening and darkening in CSS custom properties
  • Bridging color formats between front-end code and back-end APIs
  • Verifying that different format representations of a color are equivalent
  • Quickly checking the RGB values of a HEX color in a design spec

Solução de problemas

HEX value produces a different color than expected

Solução

HEX values are case-insensitive but must be exactly 3 or 6 hexadecimal digits after the #. Ensure you have not missed a character — #FF0 (3-digit) and #FF0000 (6-digit) are both valid red.

HSL hue value is out of range

Solução

HSL hue is a value from 0 to 360 degrees. Saturation and lightness are percentages (0–100%). Enter values within these ranges to get a valid color.

Alpha value in RGBA/HSLA is not working

Solução

Alpha is a value from 0 (fully transparent) to 1 (fully opaque). Values like 0.5 represent 50% opacity. Do not enter a percentage — use a decimal between 0 and 1.

Perguntas frequentes

What color formats are supported?

HEX (#RRGGBB and #RGB), RGB (rgb(r, g, b)), RGBA (rgba(r, g, b, a)), HSL (hsl(h, s%, l%)), and HSLA (hsla(h, s%, l%, a)). Enter any format and all others are calculated instantly.

What is the difference between RGB and HSL?

RGB defines colors as intensities of red, green, and blue light. HSL defines colors by hue (0–360°), saturation (0–100%), and lightness (0–100%). HSL is more intuitive for adjusting color properties — changing lightness darkens or lightens a color without affecting its hue.

When should I use RGBA instead of HEX?

Use RGBA when you need transparency (alpha channel). HEX does not natively support transparency in all browsers (HEX with alpha is #RRGGBBAA). RGBA is the most universally compatible format for transparent colors in CSS.

What does the alpha value in RGBA represent?

Alpha (the fourth value in RGBA) represents opacity: 0 is fully transparent, 1 is fully opaque. Values like 0.5 give 50% transparency, allowing the background to show through.

Can I convert CSS named colors like "cornflowerblue"?

Named CSS colors are not currently supported as input. You can find the HEX value of any named color from a CSS reference and enter the HEX value to convert to other formats.

Is there a difference between HEX shorthand (#RGB) and full HEX (#RRGGBB)?

#RGB is shorthand for #RRGGBB where each digit is doubled. #F80 equals #FF8800. Both represent the same color; shorthand is only valid when both digits of each pair are identical.

Is my data sent to a server?

No. All conversions are performed locally in your browser using JavaScript math. No data is transmitted anywhere.

Can I use this to find the HSL lightness of a color?

Yes. Enter the HEX or RGB value and the HSL output shows the lightness percentage. You can then adjust the lightness in your CSS to create lighter or darker variants of the same hue.
