This makes little sense to me.

A partially color-blind artist has no reason to amplify is dimmed color to "correct" his perceptual deficit. His brain is calibrated on his usual input. Even if his perception of (say) red is diminished, an image with the red channel amplified will look more red to him too.

A color blind person does not perceive colors dimmer or lighter, but perceives them wrong. So for example, Van Gogh would see a wheat field and pick a color that matched the wheat to paint it, according to what he saw. Turns out that this color would be orange, because to him orange and wheat both looked the same.

As a color blind myself, I see absolutely no difference between the original and the modified images. They are 100% identical to me. So I already see them as Van Gogh did. But if you can see a difference then this proves that this experiment works.

Even The Harvest was the same for you? That one I could see a large difference. The rest were more or less the same for me though.

Looking closely at the Harvest I see that that the field is different indeed. Orange in the original, and "wheat" on the modified. But that wasn't immediately apparent at first.

The Harvest is different from the others, the wheat goes from intense orange to yellow. All others are about green being replaced with yellow.
