Add new theme colors necessary for New Project Dialog on QDS

We need colors for the dialog box background, and for warning text messages.

Note: We currently don't have carefully picked colors for warning, so I used
standard yellow (ffff00). The values, for each theme, will need to be adjusted
later on.
