I never tried it, but I always thought that getting some theater lighting
'gels' could work well.

For example:

They're mostly polycarbonate, so they should thermoform easily. Maybe just
heat 'em up in an oven and drap them over the front of a warm CRT-- brush
out any creases or bubbles? (or the opposite, take an old tube with the
vaccum blown and heat up the glass and just drap the plastic sheet over the
face and work it)

In the past I've just got some window-tint from the auto-parts store and
applied it directly to the face of the CRT. It's sufficiently "stretchy"
that it still sits flat on the curve of the tube...
