The term "lilac" might be used colloquially to describe a very light or pale-colored gerbil, perhaps with a slightly pinkish hue. However, this is not a recognized or official color variety.
Is there such thing as a lilac gerbil?
No, there is no such thing as a lilac gerbil. Gerbils come in various colors, such as brown, white, black, and agouti (a combination of colors), but lilac isn't a typical gerbil color.
