Paul N. Gardner Co. Inc. has a new portable color digitizer. The Cube removes the guesswork from color matching, and makes it easy to save, store, and work with colors. A single tap of the unit produces a measurable result that can be used to match color and paint databases. Color systems the Cube works with include RGB, CMYK, HEX, LAB and LRV. The unit has a built-in, rechargeable lithium-ion battery, and sensors for color, temperature and ambient light. It will operate with clever iOS or Android phones. It will also work wirelessly via Bluetooth 4.0 or via a connection with Micro-USB.
