RED PHONES

Does anyone know why all the mobile companies have stopped releasing red phones? Idk about the general consensus about the colour but I for one absolutely loved the colour! Personally I loved the red OnePlus phones and I also owned one (OnePlus 6). They were absolute stunners but seems like its a thing of the past. I see brands release a lot of colour options but not red and it's a real head scratcher for me.is there any rational reasons as to why they r not manufacturing it anymore? Because as far as I'm informed(maybe misinformed) red phones used to sell a lot and also had a positive reactions from the masses and reviewers alike so I'm really bugged at the discontinuation of the colour.i hope they start putting out red phones again🙃
