This is a cold-tone realistic coastal landscape photograph taken at sunset in the intertidal zone. The whole scene is shrouded in soft blue-purple twilight. The foreground features fine sandy beach dotted with smooth dark rocks, and the puddles left by ebb tide reflect the faint purple glow from the sky. The middle ground shows rolling dark blue waves surging towards the shore. A huge sea stack with a natural sea arch stands on the distant sea level, the sky gradients from light pink purple to pale blue purple. The whole picture is quiet, soothing and healing, perfect for desktop wallpaper.
