Dr V, mine seems a bit worse than yours.
With regards to the red/green, the further away from each other they are the more difficult I have telling them apart. Put them right next to each other and I can sometimes figure out the colour, not always.
I do have the problem more with darker colours than lighter ones. Though Pink (looks either grey for light pink or red for dark) and Purple (blue) I insist are imaginary made up colours. Orange, well there's only one shade of Orange no matter what you tell me.
It's really wierd for me and hard to explain at times. For example, on this page I see Font colour to the right (hey, it's spelt correctly).

Take the top row. 3rd column. when I compare it to the 4th column, I can't tell the difference. However when I compare it to the 5th column, I can. BUT at the same time the 4th and 5th columns look the same to me. I can only tell the difference from the 3rd and 5th (barely, I actually have to put one on the other and go "oh it's lighter").
And 2nd row, 3rd, 4th and 5th look the same as the 1st row, 3rd, 4th and 5th. I'm looking at the picture at 800% right now trying to tell the difference.
Going down,Row 3, columns 4 and 5 look the same as each other, and very close to the ones above them. Row 4, column 1 and 2 look the same as each other (and I have no idea what colour it is truthfully). And Row 5 columns 1 and 2 look the same as each other. And this is zoomed in to 800% so it's easier. Leave it small and there's even less distinction.
It's extrememly confusing and frustrating. But at least I can tell the difference between red and green traffic lights (the green looks whitish while the red is definitely red).
That is why I borrowed my macro colour scheme off of one of the posts. Thought it looked good.
