I suppose things might have changed in ~half a century, the FDA used to care about everything.

Back in the late '80s the VAX-11/750 that was part of the Siemens MRI scanners was shipped in the old blue trim color long after DEC had switched to the very chic "brown on tan" color scheme. The FDA approval for the scanner would not let them change the color of the paint because of some bleedover of medication regulation language into the equipment approval regulations.
