Create a modern, minimalist logo for a YouTube channel called “Calmness Within,” which features content focused on relaxation, calm, meditation, and rain sounds. The logo should evoke feelings of calm and peace, incorporating smooth, flowing lines and natural elements like water, waves, or abstract representations of rain. The color palette should feature soothing hues like light blue, lavender, or soft gray. Include subtle symbols of mindfulness, like a lotus flower or a calm, meditative figure, making sure the design feels serene and in keeping with the theme of inner peace.
