Summarize the following:
Bright colors pop and get people’s attention. Add vibrant pinks, greens, or blues to the flyer so it stands out. For example, you could make the background of the flyer magenta or turquoise and add a vibrant-colored border around it. Contrasting colors are colors that are opposite on the color wheel. Colors that contrast make each other stand out, so incorporating them into your design can help people notice the flyer more easily. Some contrasting colors you could use are blue and orange, yellow and purple, and green and red. Try using only shades of blue or all reds. You don't have to use a lot of colors for the flyer to catch people's attention; people just want to look at something aesthetically pleasing. You can achieve that with one eye-catching color. A high-quality photo will get people's attention, just make sure it's relevant to the event. Avoid using photos that are blurry or low-quality. For example, if you're advertising an event at the beach, you could use a photo of a palm-tree-lined beach that has vibrant greens and blues.

Summary:
Use bold, vibrant colors in your design. Use contrasting colors to make the flyer pop. Stick to one color for a simpler flyer. Add a crisp, colorful photo to your design.
