I'm yellow/blue blind in my dominant eye. This article rings true for me, although with different colour choices. For example, I didn't realize the halo thing was common, but I see it when looking at bright pink things.
The larger an object is, the more likely I can tell from that eye alone what colour it is. Mostly I err on the side of cyan - any colour near cyan (green to light blue) will invariably look like a single shade of cyan to that eye, so those colours are pretty much indistinguishable if overlapping like in the text examples. Eg: At night, the blue lights on buses and the green "go" light at intersections are the same colour to that eye - cyan. Until they get close (large) enough and then I can tell that they are different colours.
There is a huge difference when I do A/B comparison in either case, but when looking through both eyes simultaneously, I don't notice the deficiency at all. The brain decodes colour and fills in the blanks in unusual ways.
