This is a project I completed for E-Learning Heroes Challenge #323: Interactive Coloring Books using Articulate Storyline.
I used a clipart image I found online in EMF format. I brought the image into Storyline and ungrouped the image to separate it into its component parts. That made each item editable! I defined a state for each color, then copy and pasted the state onto the other items. Finally, I added the color palette and wrote triggers to change the mouse/paintbrush color when a color is selected, and to change the state of each item when clicked upon depending on the selected color.
