Baby shower invites

Kia-Shun
I'm so crafty. Made all 200 of my wedding invites but my baby shower isn't until nov 21 (due Valentine's Day) and I've already started making my shower invites. Neutral shower (not finding out the sex) grey yellow and a pretty aqua blue ( color isn't right in pics)
The green and yellow pieces will be inserts with additional information. 
What are yal shower colors ..theme..  etc
