And here is RC2 of that plugin. I've changed a plugin syntax, because the old
seems to be too enigmatic and it was hard to me to handle unnamed parameters
in not hardcoded way. I hope that my changes are acceptable for you.
Of course, I'm open for discussion or exchange of ideas :) --[[Paweł|ptecza]]

+
+This plugin can be used to color a piece of text on Ikiwiki page.
+It's possible setting foreground and/or background color of the text.
+
+The plugin syntax is very simple. You only need to type name (e.g. `white`)
+or HTML code of colors (e.g. `#ffffff`) and a text you want to color.
+The colors should by separated using a comma character.
+You can use name (e.g. `white`) or HTML code of colors (e.g. `#ffffff`)
+to define colors.
+
+Below are a few examples:
+
+ \[[!color white,#ff0000 "White text on red background"]]
+ \[[!color foreground=white background=#ff0000 text="White text on red background"]]
+
+Foreground color is defined as a word, background color is defined as HTML
+color code.
+
+ \[[!color white "White text on default color background"]]
+
+Foreground color is default color if only one color was typed and a comma
+character is missing.
+
+ \[[!color white, "White text on default color background"]]
+ \[[!color foreground=white text="White text on default color background"]]
+
+Background color is missing, so the text is displayed on default background.
+
+ \[[!color ,#ff0000 "Default color text on red background"]]
+ \[[!color background=#ff0000 text="Default color text on red background"]]
+
+Foreground is missing, so the text has default color.
+
+This plugin is not enabled by default. You can do that in [[ikiwiki.setup]]
+file (hint: `add_plugins` variable).
