The LED's come with different color temperatures. What is listed as white may be cosidered cool white which has a blue tinge to it. Others may specify warm white which closely resembles incadescent light.
It's a matter of experimentation what looks good in different applications.
My white LED's have the frosted top and a blue tinge which look fine to me under my red and green case covers. I do have one repro jewel cap and the red does look a bit funky, but I can live with that. I learned the hard way by never switching the track by turning the jewel case cover, thus the reproduction replacement!!!!
