Whether you’re a graphic designer or just need to touch up a spot of wall paint, precise color is key. Out in the world there are endless sources of color inspiration and reference. But without a highly trained eye, matching those colors is basically a guessing game.

Nix Mini is a pocket-sized sensor that instantly gives your iPhone a precise eye for color. Just scan any colored surface, and save it to your phone or tablet. Then, you can match it to a library of more than 28,000 brand name paint colors, as well as digital color codes. And right now, you can get a Nix Mini Color Sensor for just $55.25 at Cult of Mac Deals with coupon code: GIFTSHOP15.

So whatever color catches your eye – painted walls, vinyl, leather, plastic, fabric, dyes, you name it – you can put it to use in physical or digital space. Take the color code to your hardware store, and you can get it turned into a can of paint from Benjamin Moore, Dulux, Farrow & Ball, Sherwin Williams, and more. Or, use it on graphic design or web design projects via the RGB, HEX, CMYK, and LAB formats. Additionally, the sensor itself is solid state, durable, and smaller than a ping pong ball, fitting comfortably on your keychain.
