Question
I recently overseeded my lawn.  Last summer my house was built and the contractor's mix grew into mostly crabgrass.  Over the fall, I raked up all the thatch and seeded heavily early this year (after the last snow melted).  I used tall fescue seed and it began to grow nicely, however, now my front lawn now has a Dayglo green color.  Some areas look yellow, while others are darker. My front lawn gets a lot of sun. It also seems to be growing slow.  I water 2 - 4 times per week, for about 20-30min at a time. I have also already applied some Scott's starter fertilizer.  What could cause the lime-green color?  What should I do to to get a consistent dark green color?

Answer
This is not uncommon on newly seeded lawns. apply a 2nd application of turfbuilder fertilizer now, and then change your watering pattern to 1-2 times weekly, but water more deeply, e.g. such as 60-90 minutes per application.

Apply more fertilizer next fall.
