Scoreboard colors not appearing in the tablist

When I join a minecraft server that has scoreboard teams with colors, they do not show up in the tablist. When I press tab, the names are all white. But when I join the same server in the 1.8 release, the colors show up.

There are plugins that modify scoreboards to get prefixes on the server, but even testing with the commands produced similar results.

I have provided screenshots with the tablist and the minecraft version to demonstrate. There was no change to the server's scoreboards or configurations between the two screenshots.
