Color filters can help your eyes distinguish features a bit better on the planets (Jupiter, Saturn and Mars) by enhancing contrast between various colors.
#80A Medium Blue Planetary Filter: Enhances details in Jupiter’s belts and Red Spot, high clouds and polar caps on Mars, lunar surface details, Venus cloud features
#25 Red Planetary Filter: Enhances Martian surface details in large scopes, reveals cloud definition on Venus, accentuates bluish cloud regions on Jupiter and Saturn
#58 Green Planetary Filter: Enhances contrast of blue and red structures on Jupiter (including Red Spot), melt lines around Martian polar ice caps, accentuates Saturn’s cloud belts
#15 Deep Yellow Planetary Filter: Boosts contrast of lunar features, accentuates red and orange features on Saturn, Jupiter, and Mars, reveals low-contrast cloud detail on Venus
Do not, however, expect your eyes to perform like a camera. Your eyes can only process 1/16 second exposures, cannot stack images, and has most of its color receptors (cones) shut down at night - put cameras under the same limitations and their images would not be quite as spectacular.

Colored filters are available from almost any telescope shop or online, but I agree with Brent and have not been impressed by their benefits...although I know some planetary specialists swear by them. You might try a cheap experiment with colored transparency sheet to see if they work for you before plunking down for a real set.

But first, happy to say all of my old photography filters also work. Just lay them on top of the lens and handle all carefully.
You guys are all missing Jupiter's 5th moon! My 6 year old granddaughter, who told me that Saturn's rings are made up of ice, dust and newspapers (she heard particles in school which she translated to articles and the rest is brag time), looked through the DS2114 and she said she saw FIVE moons with Jupiter. Now who am I to argue?? I think we have a budding astronomer here.
