If you wish to emphasis Text on your Buncees, there are several ways you can do so through adding shadows to your Text.
Add a Shadow Sticker
Open the media palette on a Buncee, then in the search bar at the top, type 'shadow' or 'glow'. Click here to learn more about how to access the media palette.
Select a sticker of your choice, then click 'Add'.
Drag the shadow to the asset that you'd like to emphasize, and adjust its shape & size and opacity if necessary.
Add Shadow through Duplicating Text
Click on a Text item, and then click 'Duplicate' to make a duplicate of the Text.
Change the text color of the duplicated Text. Play around with different colors!
Drag the duplicated Text on the canvas, and place it slightly above/below/to the left or right of the original text. Play around with the positioning to customize your shadow!
Adjust the opacity of the duplicated Text item, or group the two Text items together if you wish to move/edit them at the same time.
Emphasize Text by Filling Text Box
Another easy way to emphasize your Text item is to fill in the text box with a different color.
Click on a Text item once (different from double-clicking it). The Action Panel will show a 'Fill Color' option.
NOTE: Double-clicking a Text item lets you adjust the actual text content, while a single click lets you adjust the text box.
Click on 'Fill Color', then choose a preset color or a color from the color palette. Adjust the opacity if necessary.
