Reply to comment by crimeo in In Monet's impressionist paintings, that dreamy haze is air pollution, study says by WouldbeWanderer

No need to be snarky.

If cataracts just makes things look blurry then you're right.

If cataracts makes bright colors look dull, for example, then he would still choose paints that match the true colors of the scene. The bright colors in the scene would look dull to him, but his bright colored paints would look exactly as dull.

Sorry, sorry. Anyway yes to a degree, but your dynamic range would be scuffed and you'd still make more mistakes. Like by analogy, if I'm a carpenter and I try to build a set of cabinets with a ruler that only has 1 centimeter markings and no millimeters anymore, they're going to be way shittier and not line up quite right ans not close fully, etc., even though I'm consistently using the same rulers throughout. The lower precision will make the answers float around further from the true mark.

It will always just add more and more errors.

edit: or not an analogy, just the extreme version of this actual issue would be full colorblindness, i.e. grayscale. You could still paint in color but you'd have to guess which color. Partial points along that continuum will be some way in between "the right color" and "guessing"
