Kind of blue, counterpart of shocking pink? (8)

I believe the answer is:

electric

I'm a little stuck... Click here to teach me more about this clue!

'kind of blue' is the definition.
(electric blue is a shade of blue)

I cannot understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for electric that I've seen before include "Form of energy for lighting" , "Full of expectation" , "Emotionally charged" , "Energetic" , "Type of light, fire, shock, etc" .)

I've seen this clue in The Guardian.
