Tested on MediaWiki 1.43. Not sure about older versions.

Installation

Installation is pretty standard:

1. Download extension to the extensions folder.
2. Load the extension in LocalSettings.php wfLoadExtension( 'ColorizerToolVe' );

Configuration

You can customize pre-defined colors in a color picker via these configuration parameters:

$wgColorizerToolVEColorPickerTextColors = [
   "#68349A",
   "#B02418",
   "#EA3323",
   "#F5C342",
   "#FFFF54",
   "#081F5C",
   "#2F6EBA",
   "#4EADEA",
   "#4EAD5B",
   "#9FCE63",
   "#000000",
   "#595959",
   "#BFBFBF",
   "#E7E6E6",
   "#FFFFFF"
];

$wgColorizerToolVEColorPickerBackgroundColors = [
   "#DF4532",
   "#F0918E",
   "#67ABE5",
   "#A3C1E3",
   "#CDDFF6",
   "#FFFF73",
   "#FFFFCA",
   "#67AB64",
   "#A9CD71",
   "#CBDFB8",
   "#8A5EC2",
   "#B99FDA",

Place these definitions in LocalSettings.php before loading the extension to override the default palettes.

Usage

In visual edit mode go to text styles > more and you will see 2 options -- colorize text and colorize background. The last one can change both text and table cell colors.
