> Have you tried using "echo -n"?

Don't get in the habit.  Use printf(1) instead:

printf %s %'\e]4;3;255,  0,  0\a'

echo(1) is non-portable when it comes to options, and 'echo -n' will not
behave the same on all shells; you are better off learning the portable
alternative up front, in case you run into a situation where you aren't
using bash.

[I'll leave the fact that $'' is also a non-portable bash-ism for
another discussion]
