“The Color Purple” house — that’s how the actor LaChanze refers to her five-bedroom home in lower Westchester County, N.Y. This has nothing to do with the exterior (it’s gray) or the interior (plum, lavender, lilac, fuchsia, mulberry and violet are underrepresented).

But it has everything to do with LaChanze’s Tony-winning performance in the 2005 musical adaptation of Alice Walker’s celebrated novel. “Being in ‘The Color Purple’ was how I was able to buy the house,” said LaChanze, who is currently starring in the limited-run Broadway production — through Jan. 9 — of Alice Childress’s 1955 comedy-drama “Trouble in Mind.”

Her other Broadway credits include “Once on This Island” (1990),“If/Then” (2014) and “Summer: The Donna Summer Musical” (2018). She won an Emmy in 2010 for the PBS special “Handel’s Messiah Rocks: A Joyful Noise.”

Sixteen years ago, after considering various housing possibilities, LaChanze settled on the suburbs, because she wanted her children, Celia Rose Gooding, now 21, an actor, and Zaya LaChanze Gooding, 20, a college student, to have firsthand knowledge of lawns and trees. For herself, she wanted relatively new construction.
