Rainbow palm wallpaper, with several tall, slender palm trees silhouetted under a mint-colored sky and a complete rainbow stretching across the horizon. The composition is extremely minimalist, with large areas of white space allowing the gaze to naturally fall at the intersection of the rainbow and the treetops. The low-saturation teal tone layered with a hazy rainbow conveys a refreshing sense of small happiness and healing. It is suitable for users who appreciate artistic freshness and minimal aesthetics, making for a clean desktop background that does not overshadow icons.
