you can't. the bottom one is reclaimed wood type or oak and yours looks like maple. that finish would have to be completely stripped and more of a weathered type of gray/brown stain would need to be applied. but it prob won't look like the one in the picture.

please delete your other post. you have duplicates.

You can. Research "Iron Oxide" and maple wood finish (it looks like your cabinets are maple?) Iron Oxide reacts with tannins in natural woods to brown or gray it. I used "Pioneer Wood" from Rockler which is straight Iron Oxide powder you mix with water, to age my knotty Alder barn doors-took them from fresh wood to instant "reclaimed" without smell or mess. You'll need to remove any poly first from the cabinets by sanding them down and do a test piece first.

It's really hard to refinish wood that's already been sealed. Refinishing plywood panels that have already been sealed with poly is especially impossible.

If you want a taupe color why not just paint , yours will never look like the picture no matter what.
