A firework display with a blue and pink theme for a gender reveal sounds like a beautiful and exciting way to share the big news! Send out invitations with blue and pink color schemes, hinting at the theme and the excitement of the reveal.
As the finale of the fireworks display lights up the sky with a dazzling array of blue and pink, announce the gender of the baby to everyone. You could do this with a loudspeaker, or have a banner unfurl with the words “It’s a Boy!” or “It’s a Girl!”.
