Did you know? The heart is the first organ to develop inside a fetus, and it starts beating around 6 weeks after conception, which is before many other major organs have formed.

Creative Coloring Ideas:
• Here are five different color schemes for the hearts image:
• 1. Pastel Rainbow: Color each layer of the heart a pastel shade of rainbow, from red at the bottom to violet at the top.
• 2. Monochromatic: Color each layer of the heart one solid color (e.g., pink, blue, etc.), with slight shades of gray and white for shadows and highlights.
• 3. Ombre Blue: Gradually shift the color of the heart from light blue at the edges to darker blue in the center, creating an ombre effect.
• 4. Rainbow Gradient: Create a rainbow gradient by coloring each layer of the heart with slightly darker or lighter shades of red, orange, yellow, green, blue, indigo, and violet.
