"Craft an inclusive and sensory-friendly abstract coloring page designed to engage both autistic children and adults. The design should be characterized by gentle, flowing lines and soothing geometric patterns. Consider adding a variety of shapes such as circles, curves, and waves, allowing colorists to explore and express themselves freely. To cater to sensory sensitivities, ensure that the lines are not too thin or intricate, and provide ample white space to prevent visual clutter. The coloring page should encourage creativity and provide a calming experience. It's important to create a design that can be colored intuitively, allowing individuals to engage with the process in a way that suits their preferences. Keep in mind that the goal is to provide a therapeutic and enjoyable activity that celebrates the beauty of abstract art while respecting sensory needs.", no mock up, --ar 3:4
