I can't believe people are still loving obsessed with talking about this.
It's quite clearly blue and black and people saying otherwise need to either have an eye exam or need to stop loving with their monitor's brightness and contrast controls, because that will obviously have an effect and therefore doesn't portray the truth.
People need to stop discussing this because it's like watching an entire classroom full of stuff-flinging monkeys try to discuss the working of a vacuum colour. Leave colour perception to people who actually study it.
