Did you just buy them from the pet store? If they were in a tank with other colored mollies than the real father could be a different color. Or they could get their silver coloration later on as they mature.

When my platy fry were born they were white....the oldest fry is now bright orange (2 months old)...

The colour takes a few weeks to fully develop

update
Only a few fry are normal. Most of them are born already dead. I add to remove all the oder fish. Even the 2 corydora panda where eating the fry
The fry are now alone with the swordtail fry born yesterday in my 10 gallon.They don't look to good...I hope they will make it
