Key facts
The story of this color
Thor’s Thunder (#65C6EC) belongs to the Azure color family.
As a bright tone with high saturation and generous lightness, it radiates energy and optimism. Bright variations like this perform well in summer campaigns, children's products, and attention-grabbing hero sections.
Azure derives from the Arabic lazaward, referring to the lapis lazuli stone that yielded ultramarine pigment—once more costly per ounce than gold. Medieval European painters reserved ultramarine for the most sacred subjects, particularly the Virgin Mary's robes. The word azure also entered heraldry as the term for blue fields on coats of arms, symbolizing loyalty and truth.
Azure strikes a balance between the brightness of cyan and the depth of blue, making it a versatile choice for technology, aviation, and financial brands (Microsoft Azure is a prominent example). Pair azure with white for authority and clarity, or with light gold for a regal combination.
Sitting on the cool side of the spectrum (hue 197°), it promotes a feeling of calm distance and intellectual clarity, which is why cool hues dominate corporate identities, healthcare design, and productivity tools. With 78% saturation, it occupies a comfortable middle ground: colorful enough to be distinctive, yet restrained enough for extended reading or large surface areas.
Azure evokes trust, aspiration, and openness—like a clear sky. It feels less corporate than navy and more refined than bright blue, hitting a sweet spot for brands that want to appear both professional and approachable.
At 66% lightness, it reads clearly on dark backgrounds and provides a welcoming, open feel in light-themed designs—versatile across both contexts.
Use azure as the primary brand color with charcoal text for a clean SaaS identity. Create split-screen layouts with an azure panel on one side and white on the other for impactful above-the-fold sections. In icon design, azure provides excellent visibility against both light and dark backgrounds.
