Change prompt colours

[Chadley Wilson]

Greetings,

I would like to have a message displayed when users open the terminal.
This I can do! But.
I would like that message to be a certain colour,
I also want to change the prompt to a different colour,
The bash beginners guide is very clear on this.
Any suggestions :->
Thanks
