Blue lowers stress and is associated with trust, intelligence and reliability. It is the color of stability and competence, which is why so many banks, insurers and technology companies build their brands around it.

Blue dominates corporate, financial, healthcare and technology design. Light blues feel airy and clean, while deep blues convey authority and luxury. It is also the default for links and primary buttons in countless interfaces.

Ultramarine was once made from ground lapis lazuli and was more expensive than gold, reserved for the robes of the Virgin Mary in Renaissance art. Prussian blue and synthetic ultramarine later made blue affordable and ubiquitous.

Blue commonly means trust, peace, loyalty and wisdom. In some cultures it is protective, in others it signifies sadness, and it is widely used in flags and institutions to project stability.

Choose blue when you want to build trust, calm and professionalism. It is the safest choice for corporate and financial brands and for interfaces where clarity and reliability matter most.
