A lighthouse stands on a rocky cliff above rolling waves, with a big empty heart and Happy Valentine’s Day lettering in the cloudy sky. Detailed — best for teens and adults.
Rock, water, and sky need cool strength around the lighthouse: use slate and warm gray for the cliff, layered teal and navy for rolling waves, and a cloudy sky in pearl gray and powder blue. The lighthouse can be classic white with red bands or a softer cream and coral. Leave the big heart largely pink or red, and make the lettering a deeper crimson for contrast.
Give the waves movement by coloring their crests lighter and their troughs deeper, following each curve rather than filling them flat. The empty heart is an invitation: you can write a name, initials, or a short message inside it before coloring the border. Fine gray lines on the rocks and a bright lighthouse beam area complete the coastal drama.
