Notes
Blue is the most-searched color name on the web by a wide margin. The CSS value #0000ff is pure-channel blue, the bluest blue an sRGB display can show, and it is too saturated and dark for most modern interfaces. Designers usually reach for a softer mid-blue around #2563eb or #3b82f6 instead. Cultural associations are unusually consistent across regions: trust, depth, water, sky, sleep. The full-saturation value is best used sparingly. Against dark gray text it can vibrate; against white the contrast is high enough to feel sharp rather than friendly.
