I love red. I wear it a lot, I am drawn to it in any colour scheme and I recognise the power it has in any landscape to make things "pop". Some artists use red as their signature colour , signing a painting possibly devoid of statement colour with the swoosh of powerful red, intended to highlight the provenance of the painting. I like that but it's too subtle for me.
I have a love hate relationship with red. It is so powerful that it needs balance.Too much and the painting becomes visually assaulting. I posted a painting on my FB page and a friend commented on how I use red in the centre of my paintings , so I went back and had a look at some of my paintings.
I see what he means!
