Sure, that might happen.

  It's almost guaranteed to happen. Do you really think she has paints that can match any material in all parts of the visible spectrum? That's what you're asking for with this hypothetical "green to her, grey to us" paint. If she sees green, she's going to put down green paint. Furthermore, if to her these colors are the interesting part of the scene, it's natural that she'll exagerate them a bit. She's an artist for pity's sake, not a camera.

    > she's going to put down green paint. But what appears green to her may not appear green to a trichromat.

      In paint, where there's only one pigment, green is green, whoever looks at it.

        Paint pigments are not pure single-wavelength colors.

          They're not pure wavelengths but there's not many pigments. You're not going to get a cross-spectrum match.
