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.

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

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

Quite. The rating of a fuse is not the current it will blow at but the maximum current it can carry indefinitely without blowing.
