Color Purple really isn't the show to pick if you want something fun and lighthearted.
If you want a fun show, as in you want to laugh, Something Rotten is the way to go. Aladdin is also fun, as is School of Rock.
If you just want something light, you could go with On Your Feet or Matilda. Or Wicked even. (What show have you seen before?).
My friend who just saw Great Comet came out of that saying "that was fun", so it might also fit your bill.
