On my monitor your tile looks to have a pink cast. It will very hard, if not impossible, to find a switchplate to match. Between beige and white, I'd stick with the white; the wrong tone of beige will look awful.

Leutron has so many colors. Try to find one that is a close match to the tile.

The tiles have a yellow undertone, photos color are off

Ah, well that will make a big difference in terms of finding something will be a close match, or at least in the same color family. Still, I don't think the white looks bad.

You can always paint them.

Changed plugs, much better, thank you all for your comments

Almost a perfect match
