I like flowers in monochrome because then it can be any color I want it to be. This flower is becoming almost unplant-like...the darks are ominous and sparks are flying. I'd say it's color is within the crimson family.
I love flowers in monochrome -- stripped of their color, we're forced to focus on their (often) grotesque figures and forms. And so much the better when that means the flower takes on a new identity altogether. This lily has thorns!
