I laughed out loud just now reading your thread title.
I was 18 years old before I learned that I am partially red-green colorblind. I learned it by coming across a color dot test in the back of a school book.
Before then I had never even given a thought to why on earth the "whitish colored traffic lights were called "green".
Since you have been honest about your color blind quandry, I'll give you the chance to take a selfie shot of you wearing your socks and post it here.
Someone in this thread other than me will let you know if your sock color qualifies.
