I don't think that is the case now.
While general purpose LED may appear to be colder it really depends on how the quality and newer generations are very good with excellent light quality and longevity, Soraa and Yuji spring to mind immediately and they should be able to at least match 'old fashioned' lighting while giving benefits of lower running costs and running much cooler.
If you want halogen then currently the best option I believe will be Solux probably the 4700K. Relatively inexpensive solution but they run very hot
