Several years ago, at least some of us thought it was a major achievement when manufacturers introduced pens that could write in more than just blue or black ink. They were a dream come true especially for kids, artists and teachers who no longer needed to carry around separate pens for writing and correcting mistakes on their students’ tests, term papers and homework.
Cronzy is a pen that goes many steps further than most multi-color pens because it can write in pretty much any color that any user would want and can even match scanned colors also. The pen is capable of writing in more than 16 million colors, its makers say. Its main mechanism is based on solenoid valves like those used in various other devices and the pen features a special algorithm for mixing colors.
