Add ability to filter by Color

Right now I can not filter by the project field Color. We use this field to flag our projects and it is very visible if someone makes a mistake. Right now I have a report per color but I have to use the tags but if a team member forgets or types in the wrong tab it doesn't appear.

We use these reports in our weekly scrum of scrums and I would like to implement this soon so that we do not miss any projects that are incorrectly tagged.
