Paint cryo-barrels, please

[Bibliothekar]

Exploding barrels have a bright red colour that sticks out almost everywhere. Cryo-barrels on the other hand are the exact same grey as the decorative ones standing around everywhere and can only be told apart by the tiny health bar when you point directly at them. So please, could we have them painted in a bright blue that clearly marks them?

And while we're on it, how about green barrels with toxic sludge that sprays all over the area when you destroy them? :)
