The first picture does not look like walnut to me.

Although i can say for certain the bottom picture is Mahogany.

Yes to the walnut (veneer) yes to the (Philippine) mahogany.

Walnut; Mahogany.

Walnut lightens over time, finishes amber over time. That is what we are seeing.

Thanks guys. Any suggestions on achieving a similar tone on new cabinets without waiting for 50 years of ambering and/or lightening? Can walnut be stained to be a touch amber without looking bad? (I can live with the dark parts) or should I be looking for a different wood? Does modern mahogany make a decent cabinet door?

It's not exactly a trendy look right now so you don't see it in cabinetmaker catalogs. :) Thanks again!

Take a look at butternut, sometimes called "white walnut" It starts out much lighter and you can push the color darker with dyes or pigments. You can't go lighter without bleaching. Butternut has a grain structure similar to walnut, being a related species.

I'll add that to my list of species to investigate. Thank you Bob's nephew! :)
