Most women see color shades better than most men. I don’t know why. Plus I am an artist. I would never describe that as either beige or gray. Beige is a pale sandy brown. Gray is white with some black in it, no color (although it can be faintly tinted ‘cool’ or ‘warm’).
I was going to say that it looks like there may be a hint of green as olive there, but in the photo it really does look more like taupe or ecru or something along the more yellow-y lines. But cameras will color correct to what they think the proper white balance is, so in reality those doors may be greener or yellower than in the picture. Like if I correct the white balance to various points in the photo that I suspect are white or neutral gray, those doors look more definitely greenish.
I’m gonna go with dirty.
Like everyone else, I see some variety of off-white or very very very light brown.
I wonder if your girlfriend is one of those women who is a tetrachromat, meaning they have an extra color cone in their eyes that ¿most? Women and I guess no men have the genetics for.
I’m not sure about that most part for women. What I remember reading is that it’s an X chromosome mutation that requires it to be on both chromosomes to work.
Yes, I would like to change my answer now and say those doors are green! Green as the peestains in an Irishman’s underwear.
Khaki, if it was fabric. Based on Joey_P’s swatch, I’m going with taupe.
Love it!!! Can’t wait to repeat it when I run into one of my Irish friends.
Showed it to my wife. Her answer is “latte.”
I said some people saw green and she said, and I quote, “There’s no f— green there.” 
Look, there really are colours where you cannot find an equivalence between RGB and CMYK, so you just have to approximate it. Call it tobacco stained teeth at the age of 30-something, not too heavy smoker.
Remember, though, in real life the color may be different. To my eyes, this image looks like it’s color balanced a bit warm. If I set my white balance to the “white” on one of the central bags or to the bin on the bottom right, the doors look more obviously green-ish. We really have no idea what it looks like in reality unless we included an XRite Color Checker chart, a calibrated grey card, or some similar known neutral target.
I bet the GF is right here and in reality, these doors are greener than they appear in this photo.
Yea, I think your wife might need her eyes checked, there’s not even a hint of green in those doors unless the lighting in the picture hides it
The Duality of Man
Your GF is correct.
A very light value of pea green.
One of the bags is off-white.
Compare the two.
You’ll see the green.
I read it in an old Stephen King story and now it pops out of me every time green is referenced. 
Hey. Maybe your GF discovered the true hue of Puce !!
Truth be told It’s very possible that our computer monitors could all be displaying the image in a different (perhaps ever so slightly) color.
There is definitely some green in there. It is part way between pea-green and beige. Slightly closer to beige or perhaps tan. But I wouldn’t call them “green doors.”
I worry about you Dung Beetle. I worry a lot.
Yes, of course there’s some green in there. If there weren’t, it’d be some shade of magenta. It is, as @Joey_P said, #af9c7b. Which means that there’s more green than blue (9c > 7b), but also more red than green (af > 9c).
The first thing that came to mind was ‘kind of greenish-beige’. But my wife is routinely mystified by my color judgments, as are others on occasion, so I have long accepted a deficiency in that regard.
