    Blue would be a good start.

    Have you come across yellow, yet? It's lovely.

    All the complex ions for which you need to know the colours of are listed on the spec.

    I was a Q in which you weren't meant to know the colours, you were meant to work them out through electrode potentials with information given in the Q.

    Stop panicking.

    Start picnicking.
