Sorry, no I don't. I just know a bit about optics. Hopefully one of the forum experts will be along shortly to help you out.
 
When you say 'clear glass' do you mean it's not coloured?

Well, if so it can only be because the passband of the filter overlaps the bandwidth of the LEDs a bit but it will still attenuate the light a lot.
 
"Every time you try to operate one of these weird black controls that are labelled in black on a black background, a little black light lights up black to let you know you've done it" :lol:

No, the orange filter will block the blue wavelength. You won't get any illumination at all.

well on my old clocks that were orange ,i changed leds to blue and the blue lit up the screen but not blue

If you try to put blue LEDs behind an orange filter they won't show as orange - you won't get any light through!
