This is a question we get from time to time. Often, this is from confusion around filters that are included with some popular lights that are meant to cover the target light, not the actual strobe.
The reason red filters are included with target or focus lights (lights meant to help your camera focus, but not be the main source of illumination) is typically not for the image, but rather to prevent more skittish animals from being disturbed by the light.
Red lights, in general, are harder for marine organisms to see, and less likely to disturb animals that get spooked more easily. This allows us to get closer and focus without scaring them off.
So, to answer the question: generally, no. Red filters should not be mixed with primary lights, whether using strobes or video lights. That would result in red lighting which is not desirable. They can, however, be used on target or focus lights.
However, there is another technique that is used by some experienced photographers (and more often, videographers) which is to attach blue filters (AKA ambient light filters) on your lights, and use a red filter on the camera.
This can really create some beautiful colors, especially in the blues. The red filter on the camera makes up for the blue tint of the blue filter.
