WebSDSS Filters. Knowing that the color of a star is related to the wavelength of light it gives off lets you understand the meaning of the SDSS's color filters. Each filter is designed to let in light around a specific wavelength. The filters work by blocking out light at all wavelengths except those around the wavelength they are designed to see.
