Morphology
This is a compositional color name: knowing 'cobalt' (the metal/pigment source) and 'blue' lets a learner infer it denotes a shade of blue associated with cobalt. Color-naming by material or source is a common, predictable pattern across languages, so a B1 learner who knows both words can reliably understand the meaning.
Etymology
Cobalt blue is named after the metal cobalt. Old miners called a tricky ore 'kobold' (a 'goblin'), and when artists made a bright blue pigment from cobalt, the metal's name became the name of the deep 'blue' we use today.
