A 'simple watercolor same color image' typically refers to a watercolor painting where the colors used are predominantly from the same color family, creating a harmonious and cohesive look. This technique is often used in watercolor painting to achieve a sense of unity and to simplify the color palette, making the painting more approachable and visually appealing. It is a common practice in art education and can be seen in many beginner's works as well as in more advanced compositions where the artist intentionally uses a limited color palette to emphasize form and texture.
