tinge of sadness through Peter's jovial laughter.

[Tan Elaine]

There lies a well-hidden tinge of sadness through Peter's jovial laughter.

Is 'through' the correct preposition?

Thanks.

'Behind' or 'underneath' would be better (if you're looking for prepositions). You could also use something like 'underlying' - though I'm not sure about how that would work with 'tinge'...
