![]() Medium difference, also obvious to an untrained eyeĬompanion apps like this one for Color Muse, display matching paint colors in a ranked order. Very small difference, only obvious to a trained eye A smaller number is better 2 Delta E is commonly thought of as the highest the difference can be before a sharp-eyed person will notice, or the "just noticeable difference." Here's a table of the most common ranges: The difference between a color as represented by its values in a color space and that color as displayed in the real world is referred to by color scientists as Delta E. Since color sensors have varying levels of accuracy and the color reading translates the color of the paint on the wall to the not-directly-correlated RGB color scale, that's two ways errors creep in. The software assigns the closest color it can find. Paint (like all real-world colors) is reflective, not additive, so its colors don't exactly map to RGB. RGB is an additive system, however - like you learned as a toddler, red plus blue makes purple. For instance, pure yellow is composed of equal values of red and green, and adding increasing amounts of blue makes it increasingly lighter. RGB is a way of generating colors as defined by mixes of the three primaries 0,0,0 denotes black, and in an 8-bit system 255,255,255 denotes white. The $100 Nix Mini won me over, and it's the sensor I'd recommend if you're interested in paint matching. ![]() If you're looking for a way to match paint on old walls or paint new walls to match the color of an object (you can scan nearly anything with a smooth surface), these handheld devices are a big help. ![]() ![]() Nix Mini, Color Muse and Palette Pico scan a spot on your wall, connect via Bluetooth to a companion phone app and show matching paint colors from multiple paint brands.Įager to find out if these could solve my paint problems, I put these color-reading gadgets to the test. Turns out, there's a tiny piece of tech here to save the day.Ĭolor sensors that measure and match colors among real-world objects aren't new, but the three I tried are among the friendliest and least-expensive options. However, picking the right paint color or trying to match existing ones gave me major choice anxiety. I couldn't wait to get my hands on it and make it our own. My husband and I recently bought a house built just after World War II with rooms stuck in nearly every decade since. ![]()
