I don't know. The only two people I know who are colourblind have exactly the same problem; they can't tell brown and green apart so whenever we play or watch Snooker, they can't tell those two balls apart. I can't remember if they also have difficulty with the red balls... maybe. So assuming brown has quite a lot of red in it and it appears as green, I'm not sure about the greyness you suggest. I'm curious too... in a worst case scenario where someone had no red-sensitive cones at all... only green and blue... so total red colour blindness... what would they perceive on an image with three bars, like the French flag but different colours; of pure red, green, and blue... would the red bar be blank/grey/black or one of the other colours? No idea.
