How to change the color of text in a Flyer

Hello Jane, there's a couple of ways to do this. In the layer stack on the right-hand side click the text layer that you pasted. On the left-hand side you should see the Text panel with all your text options below. 

To change colour you can click the Fill box and then use the colour menu to find your colour .  As the screenshot shows, you can also click in the text box and highlight the letters to change colour.
