The design features a vibrant and welcoming greeting, "Hello Summer". The text is written in a bold, cursive font, with the word "Hello" in a larger size than "Summer", giving it a playful and friendly feel. The word "Summer" is emphasized by being in a larger font size and colored in a bright red hue. In the center of the design, there's a watermelon slice, which is a classic symbol of summer. The watermelon slice is outlined in a darker shade of red, making it stand out against the white background. The slice is detailed, showing the characteristic red flesh and green rind. The overall design is simple yet effective, using a limited color palette and clear, bold text to convey a cheerful summer message. The use of the watermelon slice adds a touch of whimsy and seasonal charm to the design.
