SYMMETRIC BEING: Color

From intuition, I think that white is black's pure visual inversion, so there's no argument there, and the systems agree. But how do I know what a perfect inverse color looks like? I have no way of testing this experimentally, and only my intuition to go on, and two of our main scientifically-based color systems seem to disagree with eachother. I really can't have much idea initially whether they might both be flawed, they both sort of look inverted to me, but they're all we have to go on, so let's examine them.
Here's one thing that casts a lot of doubt on the RGB model: when we see a wider color spectrum inverted, we see that a whole entire side of the RYB color wheel has turned mostly blue. This certainly can't be correct, I can clearly see that there are a variety of original colors, so the inverse colors that Eoj sees should be equally spectrumed.
So maybe we're leaning towards trusting our RYB instincts if anything. But MS-Paint, Adobe, Jasc, and Gimp, all invert based on RGB, so we can't even do the should-be-utterly-simple task of doing this automatically. We'll have to invert RYB manually for these simple pictures (i.e. selecting the proper color using the fill bucket in paint and filling in the areas ourselves, which we clearly could not do to a 10,000-pixiled complex image) until somebody tells me how the hell to invert a RYB picture. Here's our first look at Eoj in each system.
Notice that in the original, the sky seems lighter than the grass, so it should be darker than the grass in the inversion. But in the RGB the sky looks lighter, and in the RYB, they still look about the same. Also, the colors in the RYB look very similar; we've lost the sharp contrast between bright blue and dark green in the original; at least the RGB version maintains a big contrast between sky and grass. What's gone wrong? Let's take a look at the black and white images:
This looks like an accurate desaturation of Joe. Except his face seems to blend in more with the sky, and his feet seem to blend in just a bit more with the grass. This is partly because the color helped tell them apart (yellow on blue, vs gray on gray), but in particular the face has blended in because yellow is actually a brighter color than blue, and looks brighter even though they're the same luminosity, as you see in Joe's black & white. This is actually our whole problem with the grass not looking dark enough in either color invert above. Yellow again is a bright color, so it looks brighter than the magenta grass, even though the grass is the lighter shade you see in Eoj's desaturate, and the light red grass looks similar shade and color to the orange, because orange is a brighter color than red (light red is more similar to orange than dark green is to blue). Perhaps to truly desaturate properly, a program should take into account the brighter or darker hues!
For a quick fix to the orange/red problem, we'll just darken the orange a little and lighten the red to give us an idea. Also, since we still don't know really whether if either of the RYB or RGB inversions are correct, let's average the two results to see what they look like. So here are our best guesses at what Eoj looks like:
we could further explore Joe and his inverses by experimenting with
different colors (since different colors seem to
invert differently in the two systems), and using darker or
lighter hues (of the same luminosity), which might give us different
results. But let us move on to actual pictures. Remember
the only way we have to invert any kind of picture is the straight
RGB invert of paint, adobe, etc, so we have no choice but to use this.
While it may be incorrect, it can still give us a general idea of
what inverted photographs might look like. After all, it still
turns black to white and vice versa.
