Ummm, I don't see anything, violent or otherwise.
You don't need to interpret this, intellectually. What's your gut reaction to staring at a huge red painting with bars or squares -not as you see it on a screen but in reality, when it fills your field of vision ?
If your gut says nothing, then nothing needs to be understood. If you see red as the color of fire, blood or wounds, then you might react to the painting the same way.
