Lake Fork / Any Suggestions?

Went to Lake Fork Tuesday and Thursday of this week.Fished several bridges and
some timber out in deep water.Could see the Crappie on my Livescope but only got a few bites .Tried several colors of Jigs and soft plastics..Any suggestions on colors or should I be fishing with minnows? Thank You for your time and help in advance.

I am catching them on a purple hair jig about 30-35 feet down over 45-50 ft. Main lake channel

Thank You Sir! If I can find some I will give them a try.

I've been fishing underwater timber in same depths but tipping jig with a minnow has helped at times.
