Not at all it seems.

I wouldn't be a conspiracy theorist about it if you look at the other top color blind sites, they are the same but w/out the end ad. I picked it since I found this one has more questions, better quality pictures, and overall a slicker website. Plus, I aready knew I was partially red-green color blind prior to the test and it also knew. I'd say it's fine

It said inconclusive for mine lol

1st time I took it I had yellow/blue blindness, then I saw that some people were tryharding so I retook it.

2nd time I got normal color vision, by looking a bit more closely at the hard ones :P.

Normal color vision for me.

It says I have mild Protan but I'm not ready to believe a website that is trying to sell me expensive glasses. I don't believe I'm color blind at all.

Might as well let me tell from Alex Jones about my vitamin deficiency.

It says normal color vision.

How long did you take the test and did you calibrate your display further out of the box too ? 

Normal color vision, which is what I expected.

I made it quick and said "nothing" whenever it was hard to make out. Don't think I took longer than 1-2s per pic. My TV is in game mode, so the colors aren't as popping as usual.

I doubt I have any meaningful degree of color blindness.

edit: Took the test again on my work monitor where I'm sitting a lot closer. Still says I have mild protan but unless it tells me which ones I got wrong I won't believe it.

There were 4 images that looked all gray shades to me. Every other one I got right.
