It was hard to board the JetBlue flight home from San Juan. We even chanced missing the flight just to stay a little bit longer on the beautiful island. Puerto Rico, like its Caribbean neighborhoods, is full of vibrant colors. Strolling down rows of freshly-painted homes in Old San Juan, it's easy to see the charms of the island. Undeniably, the color that caught my eye was shades of blue. From the fierce waves of the ocean to the cobblestones in the shade, I spotted calm and relaxing blue tones at every turn.
