Colorful Vertical Stripe T-shirt Design

Create a lively and colorful vertical stripe T-shirt design in a hand-drawn watercolor style. The design should feature four vertical brushstrokes with a small gap around and between each stroke. Each brushstroke should be a different retro color that complements the others beautifully. First Brushstroke: A bright turquoise shade showcasing playful images of sailboats with billowing sails, a friendly dolphin jumping in the waves, and a warm sun peeking from the corner. Second Brushstroke: A vibrant coral color featuring images of a compass, sea turtles gliding in the water, and seashells scattered along a sandy beach. Third Brushstroke: A sunny yellow stripe depicting whimsical lighthouse illustrations, fluffy clouds, and seagulls soaring overhead. Fourth Brushstroke: A lively seafoam green with images of a colorful beach umbrella, beach balls, and tropical drinks with umbrellas, creating a fun summer vibe. Encourage creativity in layout and design elements to make this T-shirt truly unique and marketable. Remember to print this design on a white background!
