I am sorry, I got confused with the term label
sh:in checks the validating value, not values one hop away with e.g.
rdfs:label

assuming your example

_:x1 rdf:value '#FDD7E4' .
_:x1 rdfs:label 'Pig Pink'@en .
_:x1 rdfs:label 'Vaaleanpunainen'@fi .

a shape that would work for you would be something like

[] a sh:Shape ;
  sh:nodeKind sh:BlankNode ;
  sh:property [
    sh:predicate rdfs:label ;
    sh:in ( 'Pig Pink'@en 'Vaaleanpunainen'@fi)
  ]

if you want to constrain the values of a deeper level you can use a
property path (sh:path) or nest a subshape with sh:shape
