As well as being able to set the text box text and line arrow heads, it is also possible to set the shape colors and line thicknesses.
These attributes are changed using the “paint can” button (fill color); “paint brush” button (line color); and “line thickness” button. All three work in a similar way. Press the button to display a drop-down list of options, and then select the default for the next shape(s). Existing shapes can be changed by selecting the shape first, and then pressing the button and selecting the new attribute.
Line Thicknesses
All shapes have a line thickness. Linear shapes have an actual thickness. Closed shapes (e.g. polygons, ellipses, and rectangles) have perimeters. Set the line thickness by pressing the button with the three horizontal lines of different thickness. This displays a drop-down menu of different thicknesses:

Selecting different line thicknesses
Select the new thickness. The thickness is specified in pixels, which ensures the perimeter has the same visibility regardless of the zoom level. A thickness of zero does not turn the line off. Do this by setting the line color to “no line”.
Line Color
The line color can be set by pressing the “paint brush” button to display a drop down listing the available colors plus the option of “no line”:

Changing a line's color
Note that MapPoint uses a palette system which limits all shape colors to a fixed set of 40 colors.
Select “no line” to make the color “fully transparent”. Note that this is ignored if it is not applicable. For example, a closed shape cannot have its colors set to “no line” and “no fill”.
Fill Colors
The fill color is set in a similar manner, by pressing the “paint can” button to display a drop down with 40 colors plus “no fill”:

Setting a shape's fill color
Note that it is possible to set the fill color for an open freeform line (i.e. polyline). This results in a filled polygon with a gap in its perimeter (here shown in red):
