This beautiful and cheery Valentine's Day card will bring a smile to anyone's face! The outer envelope is a rich brown color with a vibrant red heart printed in the center. When you open the envelope, the card resting inside has a brilliant red background with a stunningly brilliant white heart in the forefront. When you open the card, the cheerful message of "Happy Valentine's Day!" is revealed. To bring this image to life, I'd color the envelope a vivid reddish-brown hue while the heart on the front of the envelope stands out in a bright lipstick red. Inside the card, I'd make the background a warm, passionate red while the heart being the center of attention would be a bright snow white.
