well in that case... here's something nearly that easy with far better results.
in fact, the difference between the two in simplicity is just two ingredients.
one costs $25 worth of paint and the other costs $45.
white + have store add the tint + add poly yourself.
white + add some silver & pearl metallic + add poly yourself.
ok now to remove the confusion... when ambient light is present +/or combined with light color walls and/or ceilings... even the best of pj's lose their contrast... especially when big screens resulting in lower fL's in employed.
it is your job and the screen's to maximize (use) the remaining projected light that hasn't been robbed by other sources and return it you (the viewer).
here's an extreme example of how contrast is lost when ambient light (lots) is present...
in this screenshot taken at 30 degrees off-center... we have a N9.5, N8, N7, and N3/4 screen samples (but not in that order)...
care to guess which screen sample is which?
