Hex representation of a color with alpha channel?












89















Is there a W3 or any other noteworthy standard on how to represent a color (including alpha channel) in hex format?



Is it #RGBA or #ARGB ?

In CSS 3, to quote from the spec, "there is no hexadecimal notation for an RGBA value" (see CSS Level 3 spec). Instead you can the use rgba() functional notation with decimals or percentages, e.g. rgba(255, 0, 0, 0.5) would be 50% transparent red. RGB channels are 0-255 or 0%-100%, alpha is 0-1.



In CSS 4*, you can specify the alpha channel using the 7th and 8th characters of an 8 digit hex colour, or 4th character of a 4 digit hex colour (see CSS Level 4 spec*)



Browser support as of Sept 2018




  • Firefox has supported this syntax since Firefox 49 (Mozilla bug 567283).

  • Safari has supported this syntax since Safari 10.

  • Chrome has supported this syntax since Chrome 62. For earlier versions you could enable experimental web features to use this syntax. See Chromium Issue 618472 and Webkit bug 150853.

  • Android Apps that target Android P or newer can use this syntax

  • Opera supports this syntax in Opera 52 (or Opera 39 when experimental web features are enabled).

  • IE 11 and EdgeHTML 17 (Edge 42) do not support this syntax.

It looks like there is no hex alpha format: http://www.w3.org/TR/css3-color/



Anyway, if you use a CSS preprocessor like SASS then you can pass an hex to rgba:
background:



rgba(#000, 0.5);


And the preprocessor just converts the hex code to rgb automatically.

Chrome 52+ supports alpha hex:



background: #56ff0077;


For older browsers, you'll have to use:



background-color: rgba(255, 220, 0, 0.3);

    No it doesn't, unless you enable experimental web features, because it was causing problems on Android. See my answer above for browser support details.

You could try putting the hex color into the color picker of GIMP or photo shop to get the RGB value and then using the alpha value. eg. red is #FF0000 or rgb(255,0,0) if you want red with an alpha value of .5 then rgba(255,0,0,.5).



Maybe not exactly what you wanted but hopefully helps.

    This was voted down, which seems a bit harsh. It doesn't answer the question asked, but the question doesn't say why they want to know. If they just want to use an RGBA colour in CSS, then this answer is correct.

Chrome 52+ supports alpha hex:



background: #56ff0077;


For older browsers, you'll have to use:



background-color: rgba(255, 220, 0, 0.3);

    No it doesn't, unless you enable experimental web features, because it was causing problems on Android. See my answer above for browser support details.

You could try putting the hex color into the color picker of GIMP or photo shop to get the RGB value and then using the alpha value. eg. red is #FF0000 or rgb(255,0,0) if you want red with an alpha value of .5 then rgba(255,0,0,.5).



Maybe not exactly what you wanted but hopefully helps.

    This was voted down, which seems a bit harsh. It doesn't answer the question asked, but the question doesn't say why they want to know. If they just want to use an RGBA colour in CSS, then this answer is correct.
