Wow, I feel so useful ♥! I sympathise with BB. I really like those two-strap wing-tipped Birkenstock maryjanes, myself. They have just enough sassiness and funkiness with an unobtrusive, timeless shape. (I believe they all use the same footbed, so it probably doesn't matter which ones you try on.)

I am a firm believer in Red is the New Black (For Accessories)! (Green is my second favourite colour for accessories.) Which is to say, if the shoes are any shade of red, I believe they can be worn with just about anything (certain exceptions, like forest green pants would probably look silly with them; and if you have carefully constructed an 8-piece outfit where everything from the tights to suspenders is in red and cream then olive shoes would probably seem out of place).

But still, merlot and olive shoes don't really have to *match* clothes, even if those clothes are matchy outfits such as coordinated skirts and sweaters. Either one of them would look good with essentially any colours in the traditional "autumn" family, as well as any neutrals including navy, darks with pale accents (eg pastel oxford shirts or sweaters), bright spring/Easter-looking colours. The only thing I can bring to mind that would really fail would be pastels EVERYWHERE except the shoes, like a powder-pink Jackie O suit or baby blue jogging suit. Fortunately such outfits rarely come up in real life.
