Blue is the most widely liked color and the default for trust. It lowers the sense of urgency, so it suits products that ask for confidence: money, health and software. As a mid-toned shade, Bluetiful sits comfortably in the middle: present but not heavy.

Blue stands for calm, stability, loyalty and the sky and sea. It is also the color of sadness in English (feeling blue) and, in some cultures, of protection.

Bluetiful is a confident accent. It is best as an accent, illustration or large heading color, with a lighter or darker partner for body text. Pair it with its tints and shades for a complete scale.
