P.S. I don't care about colorblind people.
If it were an artistic endeavour I would not have chosen butt ugly colours.
You asked for improved colours because what we have is not clear enough to discern accurately, I provided a suggestion.
Green with a tint of blue: Because green means go in most cultures, and the blue differentiates it for colour blind people, look at the green in traffic lights
Purple: Because Orange is too close to red, and it's not that close to green
Dark red: because it contrasts heavily with the other two colours.
It also sets up dark as impassable and light as passable as a secondary mechanic for gauging passability, rather than relying purely on colour.
If I wanted an artistic alternative: I would draw an opaque red line around the impassable areas, with a 50% translucent red area covering anything that wasn't impassable or totally passable.
Whatever helps colour blind people normally helps people who aren't colour blind. In this case it's the dual scheme of colour
and luminosity.
