It may have spider mites, it may need more light or it may need some fertilizer.

Is it the new growth or old growth, yellow or pale green?

it's new growth that is pale green.

May need more light or some diluted fertilizer. New growth that is paler than old growth usually means lack of light or nutrients. These Dracaenas don't need and are harmed by direct sun but if it is far from a window or near a north window it may need a bit more light.

To check for spider mites, gently shake it over white paper and see if anything falls off. They would be tiny specks that move. They are common on Dracaenas. They usually cause a pale speckled appearance often towards the center of leaves on new growth. From a distance the plant just looks sickly.
