Does Kindle have ‘white on black’ text feature?

Can a Kindle use ‘white on black’ text for undisturbed night reading? Or can this only be found on ipads. I like the commercial of the cute girl reading her kindle in a beach chair, but most of my reading is in bed long after my cuter girl is sound asleep. She wants an ipad, I want a kindle, but the kindle doesn’t seem to be too good at reading in bed with the lights off, unless you have a reading light accessary.
