Dark Mode is a popular UI innovation among users. It is available in many devices and software today. This is a setting that users can use to "flip" the screen. While programs may have white circles and black text, dark mode devices will have dark gray circles (not true black) and white text. It doesn't turn everything on the screen like a blurry picture, pictures still appear normal, and some programs like games don't put dark mode at all.

The problem is that when a logo uses black or dark text, the elements of the logo (usually the company name!) can get lost or obscured by the background. If you can, choose a version of your logo that uses bright colors that contrast with both white and dark backgrounds. If that's not possible, consider adding a white or bright stroke around the letters or dark elements. This white shade will not be visible on a white background but will help make dark characters more readable on a dark background.
