Default Black theme (i.e. battery saving) for Chrome/Chrome Beta?

Is there a way to make chrome or chrome beta inverted or blacked out? Recently realised that the white background on webpages must be using a lot of battery. I'd love to be able to switch this to black, like night mode in tapatalk. If anyone knows anything about this I'd appreciate it.
