No, she adds some grey paint that looks green to here, but you of course, like the bark, can only see it as grey.

- Dylan16807 12y agoBut it turns out she doesn't have that exact pigment needed to have the same uncommon spectrum, so she uses an almost perfect match that looks green to both.
- phinnaeus 12y agoSure, that might happen.
- andrewflnr 12y agoIt'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.
- fnordfnordfnord 12y ago> she's going to put down green paint. But what appears green to her may not appear green to a trichromat.
- andrewflnr 12y agoIn paint, where there's only one pigment, green is green, whoever looks at it.
- judk 12y agoPaint pigments are not pure single-wavelength colors.
- Dylan16807 12y agoThey're not pure wavelengths but there's not many pigments. You're not going to get a cross-spectrum match.
