Will Wenge solid wood flooring become lighter or darker over time?

Q: I am wanting to purchase Wenge solid wood flooring. Can you confirm whether overtime the wood will become lighter or darker? I found the Black American Walnut I laid in my old house became very pale and light over a period of 3 years and I want to avoid this happening with the Wenge.

A: One resource I have says wenge wood flooring will become lighter with exposure.
