Hand-drawn low saturation color images refer to drawings that use colors with low saturation, meaning the colors are more muted and less vibrant. This technique is often used to create a calm, soothing, or vintage aesthetic. It involves choosing colors that have less intensity and are closer to grayscale, which can make the image appear more understated and less striking. Artists and designers might use this approach to evoke certain moods or to emphasize other elements in the composition.
