How you can get colored motd in Minecraft? It's absolutely easy.
The only thing you need is a server.
Just connect with FTP client to server (or you can edit the config with Multicraft) and open server.properties file.
Then find a row with: "motd= Something.."
Great. There it is. So now you can edit your motd and color it!
Just before the text where you want the color, add "\u00A7#" (without quotes, of course)
# = Color code (like a character or number [1,2,3,...a,b,c,..])
There is a example without colors:
And this is with colors:Code:motd= My first server
It will look like on the image..Code:motd= \u00A72My \u00A71first \u00A76server
