#DFEFFC is a pale, temperate off-white. On the Color Lab it reads clean and engineered, restrained and easy to live with. It holds up as a large surface and is too pale to lead as a primary accent.
Not just a swatch — here's how #DFEFFC works with other colors. Named schemes with #DFEFFC in its natural role, and a note on why the supporting colors balance it.
