Photos show how the Brazilian Koa (Tigerwood) color will darken and blend in a 28 day time frame.  The color will continue to deepen a little more in the first 6 to 9 months to a more orangy/brownish tone.

Brazilian Cherry (Jatoba) also has a rather dramatic color change. It is recommeneded to hold off on area rugs for the first year or pull them up frequentely. Shifting ormoving furniture around some is a good idea the first year.
