lightsteelblue 4

Light Steel Blue 4 (#6E7B8B) is the deepest X11 light steel blue variant, a medium cool gray-blue that reads as a professional, serious slate blue. It anchors light steel blue palettes as a shadow or accent tone, useful in technical documentation design, software interfaces, and corporate color systems.

True blue is the world's most popular favorite color, representing trust, competence, and stability. It suppresses appetite and promotes productivity, making it ideal for work environments. Blue is the dominant color in corporate branding because it communicates reliability without emotional excess.

Medium blue is the default choice for primary buttons, navigation bars, and link text across the web. It forms the foundation of design systems for banking, insurance, and enterprise SaaS products. While universally safe, it benefits from a distinctive hue angle or saturation to avoid blending into the sea of blue brands.
