Deep wounds visual change

Making the screen darker is annoying and makes it almost impossible to see on certain maps. Would be nice if they could give this a bit of an update to make it a bit less frustrating if you're unable to mend right away. An idea I had would be the edges of the screen start of grey and as the bar goes down it slowly gets darker and the farther it goes down maybe have some blood veins pulsing or growing more visible. Would like to hear other's ideas or how mine sounds.
