Uniform

The Uniform tool (Home tab > Colour group) shades the entire selection a uniform colour.

Note:  This option is good for lines, points, and surfaces, but is not recommended for scans. Colour scans with an intensity option for better contrast. 

1. Select the object or data to be coloured. You can select and colour an entire object or a sub-section.

2. On the Home tab, in the Colour group, open the Uniform drop-down list, and select a colour.
