As Corinna already said: nope. Windows represents console colours with
only four bits: red, green, blue, bright:
http://msdn.microsoft.com/en-us/library/ms682013%28v=VS.85%29.aspx

Only thing you can do is change the resulting 16 colours in the
console properties.

(A bit of pedantry: Cygwin programs don't run on top of cmd.exe; they
run in console windows. On Windows 7 those are managed by conhost.exe.
Cmd.exe is just another program that runs in a console window.)

Conin isn't quite that useless. It works ok for programs that only
depend on stdin being a console, e.g. python, scala, and cmd.exe,
although there are quirks. With others such as the mysql client,
output does work, but you don't get a prompt because it checks whether
both stdin and stdout are consoles to decide whether to enter
interactive mode. Output will fail completely though when programs use
console-specific output functions, in particular WriteConsole and
WriteConsoleOutput.

Which programs are the problem cases for you?
