Cheerful, which is auspicious (6)

I believe the answer is:

bright

I believe this clue is a double definition.

'cheerful' is the first definition.
(thesaurus)

'is auspicious' is the second definition.
(thesaurus)

'which' is the link.

(Other definitions for bright that I've seen before include "Sparkling" , "Cheerful or quick-witted" , "Vivid - promising - smart" , "Illuminated" , "Radiant -- clever" .)

I've seen this clue in the Evening Standard.
