Translating the physical world to the digital has been a challenge, especially when it comes to things like color: Color isn’t actually all that static a thing, and the myriad displays and cameras we use can represent them in very different ways. But new gadgets from startup Nix can help cut through the confusion – the Nix line of color sensors, including the accessible Nix Mini (normally $99) and the more sophisticated Nix Pro 2 (normally $349).

These devices are deceptively simple in their use and construction, but do one job remarkably well – with a lot going on behind the scenes to make that possible. They’re main purpose is to give you a digital interpretation of an analog color, which could be the color of any surface you come across. To do this, they house a small lens and sensor inside a diamond-shaped plastic enclosure. Both the Mini and the Pro are easily pocketable, but the Mini is about the diameter of a large coin, while the Pro feels more like a golf ball in the hand.
