Rome, Georgia’s Clock Tower

I’m visiting my mother in Rome, Georgia.  I drove to the Clock Tower which is the main landmark for Rome and took some photos.  I didn’t bring my painting supplies with me in this trip, and so I ran by Michael’s and bought the bare minimum of what I needed to paint - a package of canvas panels, student grade oil paints in primary colors plus white, Payne’s Gray and Raw Umber, a small container of odorless solvent, a small bottle of medium, and several cheap brushes.  I obviously could not get my blue to look blue.  It was Ultramarine Blue.  Why does it look gray?   Maybe it’s the “student grade.”  I am going home tomorrow and will finish it then.
