Cobalt Blue
Meaning of Cobalt Blue
A rich, vivid blue colour, sometimes described as having a greenish cast; as an adjective, having this colour, as in a cobalt-blue bowl. The noun is normally written cobalt blue and also names a cobalt-based blue pigment used in painting and ceramics, commonly cobalt aluminate, CoAl2O4. Its appearance varies with the pigment, glaze, lighting and colour reference; the colour name alone does not specify one universal digital value. Thénard's blue is a pigment name, while the other alternatives below are approximate colour descriptions rather than identical shades. This term describes a colour or pigment, not the silver-grey elemental metal cobalt. Cobalt-blue is not a CSS named-colour keyword.

Origin of Cobalt Blue
An English compound of cobalt and blue; Merriam-Webster records cobalt blue from 1835. Cobalt comes from German Kobalt, associated with Kobold, an imp or goblin in miners' folklore. The pigment takes its name from its cobalt component; cobalt aluminate is also known as Thénard's blue. The hyphen is commonly used when the compound modifies another noun.
In the Genetic Learning (GL) context
GL vocabulary lessons can use cobalt-blue to connect colour descriptions with art materials, ceramic objects and digital design. Genetic Invent teams should record the actual numeric colour value and test text contrast when styling learning announcements or HBDNF reading resources. A decorative colour choice is separate from evidence about neuroplasticity or brain-cell growth.
