While the budding flowers and leaves of spring are finally introducing some color back into the Boston scenery, the Venetian island of Burano remains vibrant all year long. On Burano, small, square houses are splashed with every color on the paint palette, ensuring that even the cloudiest of days seems bright. Tourists often ferry over from Venice to behold Burano’s residential rainbow. Yet, those who wander a little further down the winding canals will find that inside houses of pink and orange and green live true Italians. They hang laundry from shuttered windows to dry in the sun and wind their way down narrow passages to get to the market, venturing to the main island only when absolutely necessary. Because it’s easy to live simply when your life is already in color.
