I'm red-green blind but had no issue telling the plot lines apart, because the two lines have different contrast. Try converting the image to grayscale and you'll see that they are different. I'm genuinely curious: why did you have trouble telling them apart?

Depends on the person. I have trouble with red and green traffic lights, despite what others have indicated are clear contrast/brightness differences. I use the position of the lights and Tesla’s green light detector to combat this. Aren’t eyes weird?

I'm over 50, and have gotten used to using color as a way to distinguish rather than exact shades.

So I'm missing the cue I naturally relay on, and my vision is sufficiently blurry to make the one that was available hard to use.
