Official Flag of Israel Hat

The flag of Israel (Hebrew: דגל ישראלDegel Yisra'el; Arabic: علم إسرائيلʿAlam Israʼīl) was adopted on October 28, 1948, five months after the establishment of the State of Israel. It depicts a blue hexagram on a white background, between two horizontal blue stripes.

The blue colour is described as "dark sky-blue",[1] and varies from flag to flag, ranging from a hue of pure blue, sometimes shaded almost as dark as navy blue, to hues about 75% toward pure cyan and shades as light as very light blue.[2] The flag was designed for the Zionist Movement in 1891. The basic design recalls the Tallit (טַלִּית‎), the Jewish prayer shawl, which is white with black or blue stripes. The symbol in the center represents the Star of David (Magen David, מָגֵן דָּוִד), a Jewish symbol dating from late medieval Prague, which was adopted by the First Zionist Congress in 1897.[1]

In 2007, an Israeli flag measuring 660 m × 100 m (2,170 ft × 330 ft) and weighing 5.2 tonnes (5.7 short tons) was unfurled near the ancient Jewish fortress of Masada, breaking the world record for the largest flag.[3]
