Color Scheme for code not working - Sublime Text 2

You can also set the coding language by clicking the bottom right corner "Plain Text" to open a list of languages to choose from. Click the relevant language and the Sublime will do the coloring according to your selection.

If you are just opening new files and pasting text in, the default syntax is "Plain Text", thus no highlighting. You can set the syntax in the buffer by opening the command palette and searching for "Set Syntax: ". If that isn't what is happening, please try to give more information.
