Color filters can be very useful for enhancing your views of the Moon and the planets. Depending on the atmospheric conditions, the telescope being used, the observer's experience, and the planet being observed or photographed, the advantages of color filters can be anywhere from subtle to dramatic. The right filter can make all the difference between seeing several small craters in the floor of Clavius on the Moon or not; seeing five or six swirls in Jupiter's belts or not; or whether you can see inner Crepe Ring of Saturn or not.
Antares #56 Dark Green filter . They thread into the barrels of virtually any 1.25" telescope eyepiece. Each filter cell has a male and female 1.25" filter thread (M28.5x0.6) on opposite sides, so multiple filters can be stacked to achieve selective filtration of the visual color spectrum.

The #56 Green Filter is excellent for the observation of Martian polar ice caps and for the dust storms on the planet's surface, strongly increasing their contrast. It also brings out the red and blue regions such as the Great Red Spot on Jupiter in contrast to the lighter portions. It is useful for observing the low-contrast hues of blue and red in the Jovian atmosphere. The filter enhances Saturn's cloud belts and polar regions and increases contrast of cloud patterns on Venus. This filter is good for lunar observing as well. The filter may not yield good results on small telescopes.
