Set Fill Tolerance Level
Control the matching of the fill color in relation to the surrounding colors. A fill tolerance of zero means an exact color match. A tolerance level above zero matches similar colors. The higher the number the less precise the match needs to be.

2. Select Styles group > Effects > Tolerance > Select tolerance percentage > Click on canvas to apply color.

Set Fill Transparency Level
Control the saturation of the fill color. The higher the percentage number the less transparent and more saturated the color will be.

This option is a build up
effect. Therefore, when desiring a more transparent look, you need to start out
with a higher transparency percentage (lower saturation) and work your way up to
the desired color effect.
1. Select Draw tab > Drawing Tools group > Fill tool.
2. Select Styles group > Effects > Tolerance > Select tolerance percentage.
3. Click on canvas to apply color. Since this is a build up effect, continue clicking on canvas to apply another layer of color.
