I've just posted a new plugin called Color Browser. It's similar to ColourChooser but it has much more functionality. If you do any work with colors in Java code or CSS/HTML files you may want to take a look.
Here is the contents of the README:
NOTE: This version requires IDEA to be executed with JDK 1.5.0 or greater.
+ Color Browser
This plugin allows you to see colors used in Java code and CSS/HTML files. You may also picks colors and insert one of several representations of that color in the current editor.
Use IDEA's plugin manager to install the latest version of the plugin.
++ User Interface
Simply open the Color Browser tool window to begin using the plugin. The interface includes a color chooser with several methods of picking a color. As a color is selected a series of buttons are updated with different representations of the color. Clicking on a button inserts the text of the
button label in the current editor. If the editor has a selection, the contents of the selection are replaced.
+++ Color Information
In the upper left corner is a large rectangle showing the selected color along with its RGB, HSB, and HSL representations.
+++ Java Color
Below the color information is a column of buttons. These button represent the various java.awt.Color contructors that can be used to created the selected color. The last button shows one of the java.awt.Color color constants. If the selected color doesn't have a predefined constants then the button is disabled.
+++ CSS/HTML Colors
The top right section contains a column of buttons to be used in CSS and HTML files. Each button represents one of the supported color formats as defined in CSS Level 3. The last button is for a SVG color name. This button is disabled if the selected color doesn't have an associated SVG name.
Pressing the Cursor button will look at the text around the cursor in the current text editor. If the text represents one of the supported color representations the color will be selected in the tool window.
+++ Color Chooser
The color chooser contain several tabs for selecting a color in different ways. The current methods are:
HSB (Hue, Saturation, Brightness)
RBG (Red, Green, Blue)
HSL (Hue, Saturation, Lightness)
Hex (Red, Green, Blue)
SVG Colors (drop down list)
Java Color Constants (drop down list)
Pressing and holding down the Ctrl key while moving the mouse cursor around in an editor will display a hyperlink and information window whenever the cursor is over any valid color representation in one of the supported formats.
Clicking the left mouse button while a link is displayed will perform the same function as pressing the Cursor button with the caret in the same location as the mouse click.
