New Delhi: There are beautiful cities around the world to explore which we haven't even heard off. While landscapes and natural beauty are always a delight to watch, man made, and concrete buildings may also be a good option for sight seeing.And when it comes to colourful cities composed of coloured buildings as if taken out of a crayola box, it is all the more pleasing to the eye.Here is a list of ten cities which will please your eyes: 1. Pink city, Jaipur, India The city was founded on 18 November 1727 by Maharaja Sawai Jai Singh II, the ruler of Amber, after whom the city has been named.The city is full of royal palaces and various tourist destinations.The city was painted pink when Edward, the Prince of Wales, came during a diplomatic visit in 1853. The Rajasthani capital retains its signature rose-tinted hue across broad boulevards and historic buildings like the Hawa Mahal. 2. Chefchaouen, Morocco Chefchaouen, a city in Morocco is known for buildings with blue hues. The city was founded in 1471, as a small fortress which still exists to this day, by Moulay Ali Ben Moussa Ben Rached El Alami to fight the Portuguese invasions of northern Morocco. The town is situated in the Rif Mountains, just inland from Tangier and Tetouan. 3. Izamal, Mexico Known as the yellow city, the place is situated in Mexican state of Yucatán.

Balat, Istanbul Balat is the traditional Jewish quarter in the Fatih district of Istanbul. It is located on the European side of Istanbul, in the old city on the historic peninsula, on the western bank of the Golden Horn.The colourful buildings with old architecture take you to the Victorian age. 6. Júzcar, Spain It's a town in Malaga, in southern Spain. The town was white earlier but in spring 2011, buildings in the town (including the church and gravestones) were painted smurf-blue by Sony Pictures to celebrate the premiere of the Smurfs movie. 7. South Beach, Miami Neon lights, frothy façades, quirky patterned lifeguard stands, Art Deco buildings—driving along Ocean Drive in Miami is a retro trip back to an era when Technicolor was just bursting onto screens. Flamingo pinks and tropical greens flank the white sand on one side, with azure waters on the other. 8. Rio de Janeiro In 2010, Dutch artists Haas & Hahn schemed to turn a favela in Rio de Janeiro into a giant canvas for their third project in that city's slums. Enlisting the help of local youth, they converted the homes of Favela Santa Maria into a rainbow of staggering proportions, composed of rays in myriad shades radiating across the façades. 9. Willemstad, Curaçao Legend has it that in the 1800s, when the Dutch ruled Curaçao, the then-governor attributed the migraines that afflicted him to the powerful Caribbean sun reflecting off the colony's stark walls. The result? An official decree that commanded citizens to paint the structures anything but white. Today, this World Heritage site owes its distinctive pastel shades to one man's maladies.10. Vernazza, ItalyThese postcard-perfect pastel pink, lemon yellow, and sea green façades were hit by devastating floods in 2011. While the damage to Vernazza and the four other scenic waterfront villages that make up Cinque Terre was severe, efforts are under way to restore, rebuild—and repaint.
