In the munsell color order system, colors are ordered based on three attributes: hue, value and chroma. All three attributes are intended to be perceptually uniform. With equal hue or equal value or equal chroma or other rules, you can easily create harmonious color combinations.

The build in color inspector allows you to view detail color info (Munsell, RGB, HEX and CMYK color values) of any color sample you point to. Also you can easily copy the color values with handy shortcuts.

-Color accuracy
mColorBook is not just a colorful book, with its build in color management, it is dedicated to show you the color that should be.
