'looks far more cheerful' is the definition.
I can't judge whether this definition defines the answer.

'pale given a drink' is the wordplay.
'pale' becomes 'light' (similar in meaning).
'given' means one lot of letters go next to another.
'a drink' becomes 'sup' (to sup is to drink).
'light'+'sup'='LIGHTS UP'
