How to have multiple colors in a Windows batch file?
If you have a modern Windows (that has powershell installed), the following may work fine as well
call :PrintBright Something Something
(do actual batch stuff here)
call :PrintBright Done!
goto :eof
:PrintBright
powershell -Command Write-Host "%*" -foreground "White"
Adjust the color as you see fit.
jeb's edited answer comes close to solving all the issues. But it has problems with the following strings:
"a\b\"
"a/b/"
"\"
"/"
"."
".."
"c:"
I've modified his technique to something that I think can truly handle any string of printable characters, except for length limitations.
Other improvements:
Uses the %TEMP% location for the temp file, so no longer need write access to the current directory.
Created 2 variants, one takes a string literal, the other the name of a variable containing the string. The variable version is generally less convenient, but it eliminates some special character escape issues.
Added the /n option as an optional 3rd parameter to append a newline at the end of the output.
Backspace does not work across a line break, so the technique can have problems if the line wraps. For example, printing a string with length between 74 - 79 will not work properly if the console has a line width of 80.

UPDATE 2012-11-27
This method fails on XP because FINDSTR displays backspace as a period on the screen. jeb's original answer works on XP, albeit with the limitations already noted
UPDATE 2012-12-14
There has been a lot of development activity at DosTips and SS64. It turns out that FINDSTR also corrupts file names containing extended ASCII if supplied on the command line. I've updated my FINDSTR Q&A.
Below is a version that works on XP and supports ALL single byte characters except 0x00 (nul), 0x0A (linefeed), and 0x0D (carriage return). However, when running on XP, most control characters will display as dots. This is an inherent feature of FINDSTR on XP that cannot be avoided.
Unfortunately, adding support for XP and for extended ASCII characters slows the routine down :-(
Just for fun, I grabbed some color ASCII art from joan stark's ASCII Art Gallery and adapted it for use with ColorPrint. I added a :c entry point just for shorthand, and to handle an issue with quote literals.

It uses the color feature of the findstr command.
Findstr can be configured to output line numbers or filenames in a defined color.
So I first create a file with the text as filename, and the content is a single <backspace> character (ASCII 8).
Then I search all non empty lines in the file and in nul, so the filename will be output in the correct color appended with a colon, but the colon is immediatly removed by the <backspace>.
EDIT: One year later ... all characters are valid
@echo off
setlocal EnableDelayedExpansion
for /F "tokens=1,2 delims=#" %%a in ('"prompt #$H#$E# & echo on & for %%b in (1) do rem"') do (
set "DEL=%%a"
)
rem Prepare a file "X" with only one dot
<nul > X set /p ".=."
call :color 1a "a"
call :color 1b "b"
call :color 1c "^!<>&| %%%%"*?"
exit /b
:color
set "param=^%~2" !
set "param=!param:"=\"!"
findstr /p /A:%1 "." "!param!\..\X" nul
<nul set /p ".=%DEL%%DEL%%DEL%%DEL%%DEL%%DEL%%DEL%"
exit /b
This uses the rule for valid path/filenames.
If a \..\ is in the path the prefixed elemet will be removed completly and it's not necessary that this element contains only valid filename characters.
Actually this can be done without creating a temporary file. The method described by jeb and dbenham will work even with a target file that contains no backspaces. The critical point is that the line recognized by findstr.exe must not end with a CRLF. So the obvious text file to scan with a line not ending with a CRLF is the invoking batch itself, provided that we end it with such a line! Here's an updated example script working this way...
Changes from the previous example:
- Uses a single dash on the last line as the searchable string. (Must be short and not appear anywhere else like this in the batch.)
- Renamed routines and variables to be a little more object-oriented :-)
- Removed one call level, to slightly improve performance.
- Added comments (Beginning with :# to look more like most other scripting languages.)

PS. I'm having a problem with the output of the ! character that you did not have in the previous example. (Or at least you did not have the same symptoms.) To be investigated.
