TCP Writeline w/ Colors?

When running a tcp server, and someone else using a Client like Zmud, how can I use writeline, etc to display colors? when i do:
writeline c\strea, "Hello"+ColorRed()+" how are you etc" it writes Hello32 how are you etc to the client?

and one other question...
how can i writeline message, then writeline message again so it would be on the same line??

Okay well i found out how zmud/rom etc do it.
Rom puts out a string of characters that determine the color etc. If anyones curious as to the color codes that zmud uses lemme know.
