Progress bars can be broken into two or more ranges, each of a different color. For example, if a progress bar can take a value between 0 and 10 and is divided into three ranges: red, green, and blue, then the RangeCount property is 3, and the related properties are listed in the following table.
| Index | Color | RangeValue | Range | 
| 0 | Red | 0 | 0 - 3 | 
| 1 | Green | 4 | 4 - 7 | 
| 2 | Blue | 8 | 8-10 |
