First couple layers were messy and the underside looks bad, but the rest of the file prints perfect. Its the stamped writing in the bottom obviously requires support or looks messy with a hole showing the infill.
From what I can tell the object doesn't split into parts well for colouring (other than manual colouring). By the sounds of your description, I thought it would be an easier coloured model, just want to make sure I didn't miss something.
