Aqua, water in Latin, is a variation of cyan that sits between green and blue in the color wheel. Because the colors are regarded so closely, cyan and aqua are used interchangeably in web design.
Aqua has a vibrant, striking tone, making it a wonderful accent in designs. You can combine it with other cool colors like dark grays or black, or you can pair it with warm colors like yellows or bright oranges for something that pops.
Aqua evokes feelings of reinvigoration, youth, and dreaminess.
