Look in craft shop for coloured celluloid. Cut a bit to the size of the perspex window on the front panel, and attach it; maybe with some clear double-sided sticky-tape squares from the same source.
Choose the colour carefully - a colour close to that of the illuminated digits (ie. blue, green or clear) will transmit most of the light maintaining the brightness. A distant colour such as orange may render the digits almost black.
Ever heard how pilots train to fly at night ? The aircraft windscreen is tinted one colour (blue I think) and the student wears lenses tinted the opposite colour (orange) rendering the view outside dark to the student but not to the instructor.
