Journalist Staci Kramer interviewed Jeff Bezos about The Kindle. One of the questions she asked him was: “Is color something you want to see eventually?”
Kindle evangelist Jeff Bezos, chairman and CEO of Amazon responds: “We would love to have color but electronic ink doesn’t do color.”
So what is electronic ink you asked? The source of the electronic ink for Kindle explains it as follows on their website:
An Electronic Paper Display is a display that possess a paper-like high contrast appearance, ultra-low power consumption, and a thin, light form. It gives the viewer the experience of reading from paper, while having the power of updatable information.
EPDs are a technology enabled by electronic ink – ink that carries a charge enabling it to be updated through electronics. Electronic ink is ideally suited for EPDs as it is a reflective technology which requires no front or backlight, is viewable under a wide range of lighting conditions, including direct sunlight, and requires no power to maintain an image.

From what I have learned adding color to electronic ink isn’t yet on the horizon. Let me know if you have an information that indicates it might be closer to being a reality.
