I opened Adobe Illustrator and created a new document, making sure to choose the right size and layout for the flyer. I then selected a color palette that would convey the desired tone and mood for the flyer. I used the text tool to add the copy, making sure to choose a font that complemented the overall design. I added some custom shapes with the shape tool, and used the gradient tool to add depth and dimension to the design. Finally, I carefully selected the colors from my chosen palette.
