This Sim had a major role in some of Lifesimmer's let's plays.
Indigo's story is that she desires to be in the present, although she was born using a new format in Oasis Landing: Constructing a DNA Baby in the hospital. She has her mother's hair color and she used to sleep in her parent's room when she was a baby and toddler.
Indigo has a younger adoptive sister, named Violet Freeman who's currently a teenager.
Both Indigo and Violet were named after colors (which are 2 of the 7 rainbow colors), hence Violet having purple highlights on her hair and Indigo having an indigo (deep blue) and white outfit as her everyday wear.
When Indigo became a Young Adult, LifeSimmer gave her the Green Thumb trait and the Perfect Garden Lifetime Wish, because she explained that she had never been very involved with the gardening skill and she wanted to try it out with Indigo.
