This is a remix of thing:1719411. I added a backing plate. If you print the first 1.10 mm with a background color and then pause and change the filament to red and resume printing it will look good.
if you use Simplify3D and go to the advanced tab and tell it to stop printing at 1.10 mm. Then print it; when it finishes change the filament color to red. Then go back to the advanced tab uncheck the stop printing at box and turn on the start print value to 0.90 and print the rest of it.
