A Sublime Text plugin that converts CSS numerical color values. You can convert any hex, rgb(a) or hsl(a) color in the following sequence: hex -> rgba -> hsla -> hex (etc).

You can easily install the pluing through Will Bond's excellent Package Control (https://sublime.wbond.net/). If you want to install this plugin manually for some reason, simply clone this repo into your packages directory (make sure not to put it in the user sub dir).

1. Select a color declaration (e.g. '#ff0022', 'rgb(120, 0, 12)', or 'hsla(320, 75%, 10%, 0.2)')
2. Hit ctrl+shift+c by default (cmd+shift+c on Mac OS) to convert to the next type (hex -> rgba -> hsla -> hex -> etc).

• Convert hex values to rgba
• Convert rgb(a) values to hsla
• Convert hsl(a) values to hex
• Remembers the alpha value of a selection (e.g. when 'rgba(120, 0, 12, 0.2)' is converted to any other value, the '0.2' alpha value will be remembered, even if you convert the value to hex)

• Convert all colors equal to the selected one in the document (milestone 1.2)

1. CSS color names (e.g. 'red', 'transparent', etc) are currently not supported (not planning to unless there's a high demand).
2. Whenever possible, the plugin will output the shorthand hex value (e.g. '#000' instead of '#000000').
3. All 'rgb' and 'hsl' values will always be written as 'rgba' and 'hsla'. Every browser that supports rgb/hsl also supports rgba/hsla, so opaque colors simple get an alpha of 1.0.
4. The output for hsl and alpha channels is in floating point, to ensure a little more accuracy.

color: rgba(128, 0, 12, 0.5);

Will convert to:

color: hsla(354.4, 100.0%, 25.1%, 0.5);
color: #80000b;
color: rgba(128, 0, 12, 0.5);
