If an object absorbs light of most visible frequencies (absorbs because the light's frequency matches electron's frequency), and reflects red, for example, the object appears red. (reflect because red falls below or above the electron's natural frequencies).
Frequency is generally measured in Hertz, which are units of cycles per second. Color is the frequency of visible light, and it ranges from 430 trillion Hertz (which is red) to 750 trillion Hertz (which is violet). Waves can also go beyond and below those frequencies, but they're not visible to the human eye.
