摘要：
A head for an oral care implement comprises a number of colored filaments of different types. The filaments extend from a mounting surface of the head and are grouped together to define an initial color pattern. At least two types of filament have staggered time-controlled color changing properties, wherein each of said type of filament changes its color within pre-defined time periods, the pre-defined time periods being different from each other so that the initial color pattern changes color characteristics over at least a first pre-defined period of time to a first color pattern and over a subsequent second pre-defined period of time to a second color pattern, the second pattern being different from the first pattern.
