I don’t know if there was a basis for the green, blue, yellow color scheme for status, but I’m recommending a change. These colors don’t intuitively mean anything (at least not to me). Many “dashboards” use a stoplight color scheme, and I think this would be beneficial.
Red = Completed (i.e. needs to be approved/awarded)
Yellow = Completed and Approved by a leader (i.e. approved and needs to be purchased/awarded)
Green = Completed, Approved, and Awarded (i.e. has been awarded, and don’t worry about it any more)
