Y'know I'd love love LOVE an e-reader with a red light.
Not a warm white light, not an orange light, not a yellow light; a RRRED light. Like, the colour red. As in red LEDs.
Decades of insomnia only alleviated by using a rooted phone with a red-subpixels-only option have ruined me for anything else.
Out of all the e-ink e-readers ever made, guess how many you can read at night without throwing your melatonin secretion all out of whack and keeping you awake? Zero. Not a single one. Even though it'd be easy as hell. Even though out of all the LED colours, red is the cheapest and uses the least energy.
What the hell, ereader manufacturers?
Well... I've always used my e-paper-based readers without the built-in lighting, so they just have whatever ambient light I'm using.
Are you using a backlit LCD reader?
