The Chameleon Pen is a device that really truly lives up to its name, seeing as how it is able to produce a variety of different color tones and seamlessly blend them all together using just the single pen. It's pretty incredible because the ink that is produced changes its tone of color right in front of your eyes, getting darker over time as the toner dissipates.
The reason the Chameleon Pen is able to do this has to do with its special combination of alcohol ink and toner, which are used together in a mixing nib. This means that the pen can be used as a regular color pen or be used to produce softer and paler shades that darken over time.
This pen will allow artists and designers to express their visual ideas in ways they couldn't previously
