Some use different bulbs, some lights do still use "filters". I have tried them all and had good luck with all of them too. The color is not specific to the species of animal you are after.
Here is my take: I believe, based on my experience, that if you hunt the same areas animals can/might get used to the colors and you will notice they start to get cautious.
Before I got night vision I started out using red on a LightForce set up. I didn't go to the same spots night after night, but I would hit them at least each week. Even gray fox would act spooky and slow when using red lenses about half way thru the season. I switched to green and they were "bold" again. Same with the red fox. By the end of season they were starting to get spooky again with the green light. By then it was all but over, so I didn't care. Even tried a blue lens, but that didn't really let much light thru. I do still use blue lights for walking in and out. It seems to be the least alarming to animals at night.
Orange or amber is for finding raccoons in trees at night. It also helps in the summer when coon hunting to keep the bugs away. Unfortunately, it doesn't seem to deter those big. pain inflicting horse hornets. I have not tried it for predator calling, I believe it is probably too bright to work really good for predators.
This reminds me of another point that is very important when using colored lights...it is always best if you have a variable switch to turn down {or up} the amount of light you are using. This will help with animals that are spooky about lights, if you only use just enough to see. I used that LightForce light most of the time so low that almost all I could see was eye reflection and often didn't know what the animal was until I shot it. You also want to avoid shining a tight focused center of concentrated light right into the animals eyes. If you can adjust your light to be a little wider and not so coned down and/or keep the animal out of the center and in the "halo" of the light, that helps a lot too.
Many animals are so spooky about light at night that it will not matter what color you have if you hit them with a bright concentrated spot right in the eyes.
