Designing a Dark Theme for OLED iPhones

Vidit Bhargava (via Ryan Jones):

In an OLED display, the black pixel is essentially a pixel that’s turned off. It doesn’t consume any power. This is why OLED are able to show such rich dark colours and why dark themes are power-efficient.

However, When an interface that uses a black theme for its background starts displaying content on the screen, the pixels needs to switch on before they can display the content. So, when you’re scrolling through the content in a black background, the pixels find it hard to keep pace with your scrolling, resulting in a smear on the screen.

He solves this by using dark grey, which still uses significantly less power than white.
