You may consider trying Apache Chainsaw (http://logging.apache.org/chainsaw/index.html) if you are already working with log4j. Lets you define colors and filtern and works with (nearly) zero configuration.

As already pointed out by @Benjamin Grep Console is a great way to colorize output in the Console.

I had made a short video to demonstrate how it worked and heard back from the Creator of the Grep Console plugin. He mentioned that Grep console 3 is has been released.

You can use ANSI Escape in Console plugin for Eclipse. You'll need this so the Eclipse console can interpret ANSI Escape codes. Install it and restart Eclipse. Then you can use ANSI Color Codes to write in a certain color. Here's a list of ANSI Color Codes from another stackoverflow answer. Then you can do this:

public static final String ANSI_RESET = "\u001B[0m";
public static final String ANSI_RED = "\u001B[31m";

public static void main(String[] args) {
    System.out.println(ANSI_RED + "This text is red!" + ANSI_RESET);
}

I used this to create a Custom Formatter for the Console Handler so it shows logs from Logger in different levels with different colors (INFO logs in cyan, WARNING logs in yellow and SEVERE logs in red). Here's how I did it, if you're interested.
