DPC, that is one hell of a PM2 collection! I am certainly jealous!
Atakdog, two things. First, to me, the blurple is an awesome color. I love blue and purple, so I love that color. It is definitely more blue to me, so don't worry that it's a girly purple color (I know you can't tell being colorblind). No one will judge you for having this color of knife, if that's what you're worried about.
Second, I recently did some research into colorblindness, after learning a good friend is colorblind. I sympathize with you, man. Those of us with normal vision take colors for granted. I watched some videos and saw some pictures that are supposed to approximate what someone with colorblindness sees. It's very drab by comparison. Have you ever heard of EnChroma glasses? They are glasses/sunglasses that allow people with colorblindness to see colors, including purple. There are lots of videos on YouTube of people trying them out, some without prior knowledge of what they were doing (surprises from other people who didn't tell them what was about to happen).
It is pretty profound watching people see colors for the first time, especially purple. Apparently purple is one of the colors most affected by colorblindness. It's pretty amazing to see colorblind people see purple for the first time. It absolutely blows their mind, with many of them breaking down into tears. That is what made me go off on this tangent. If you haven't ever tried those glasses, they might be worth looking into. I think they are around $200-400, and if you don't see purple, they may make you love these blurple knives even more. Sorry for going off topic.
I hope this is kosher to post a video link. If not, let me know and I'll remove it. Here are some videos of people seeing color for the first time:
