The Fill Tool makes it easy to change the colour of any page, as well as change the colour of text and shapes.
Fill Tool button:
Once you have selected the Fill Tool from the toolbox, choose a colour from the colour palette. (Hint: Right-click any of the colours for even more options.)
When you have a colour selected, simply click on the object you wish to change. For this example, let’s change the inner, yellow part of this circle to purple. Note that the cursor has changed to indicate the Fill Tool is in use.
You can use the Fill Tool to change the outer line of a shape as well.
