OK, so have a weird one. Customer is looking to have an illuminated monument sign, that appears to match his building in the daytime, and illuminates at night. His building is primarily black windows. They "need" the sign to be purple. I'm aware of where purple falls on the visibility wavelength. What I'm thinking about doing is fabricating an acrylic cube using black day/night acrylic, doubling the number of LEDS inside, and placing 2nd surface doublestruck purple clear vinyl on the interior/2nd surface. Dimensional letters would be studded to the face of the acrylic. My questions are: 1. Will day/night acrylic illuminate purple with clear purple vinyl 2nd surface? 2. Will the illumination be bright enough to silhouette the dimensional letters? With standard amount of LEDS? With increased number of LEDs? Customer mentioned possibly wanting a washout effect on top or bottom of sign. 1. Is the best way to duplicate that using exterior LED lightbars pointed at top and bottom, first surface? If we illuminate day/night acrylic on the outside, will it appear black? Or will the backlit behind it prevent it from being viewed as black? 2. Easier way is probably just doing a fade on the 2nd surface trans vinyl. Any thoughts? We don't use a lot of day/night so I'm lacking on specific uses.
