Design a collection of PNG clipart images featuring a variety of vegetables. Each illustration should capture the unique characteristics and textures of the vegetables, including leafy greens, root vegetables, and vibrant peppers. Employ a modern and minimalistic style, using clean lines and a limited color palette to convey the essence of each vegetable. The clipart should be versatile and suitable for use in digital and print media, such as infographics, recipe books, or gardening resources.
