Peace lilies typically have dark green leaves. Though with dozens of varieties out there, some are variegated with hues of silver, white, green, and cream. Certain types may have light green or white foliage. Occasionally, leaves can even transform over time. However, if the texture as well as the color changes, there is likely a problem.
Aphids, mealybugs, and spider mites are common peace lily enemies. If white blotches, dust, or fuzz develop, there's a good chance you have an insect infestation. Wiping the leaves off or using insecticide can help, but if the colony is large, you may want to get rid of the plant to avoid contaminating other houseplants.
