Tanganyika and Zanzibar merged to form a new republic on 26 April 1964, the name "Tanzania" being adopted on 29 October 1964. Like the name of the country, the new flag was a merger of that of its constituent parts. The lower green stripe of the former Tanganyika flag took the blue of the Zanzibar flag, and the stripes were re-arranged diagonally to give them equal status.

The colour specifications are:

Green Pantone 361c 
Yellow Pantone 116c 
Blue Pantone 299c 
These are, of course, rather standard shades of colours except for the blue, which is lighter than "normal" blue, but not as light as "light blue". Ratio length to breadth: three to two e.g. 3' x 2', 6' x 4', 12' x 8' 


Green - Yellow - Black and Blue, having the black centre stripe centred on (the) diagonal raising from flag mast to top edge of the fly, two smaller yellow stripes dividing the upper triangle portion which is green and the lower triangle portion which is blue. 

Proportions of colours: 

Black centre stripe, centred on diagonal of flag of 6' x 4', is 13/48 of fly and 13" wide (my note - 4 feet = 48 inches).  Yellow stripes are each 1/16 of fly and 3" wide.  Colour code and significance:  B.S. (referring to the British Standard Range of colours now redundant) No. 2660, 1955 

Black   BS No, 9-103 = the People 
Green  BS No. 0-010 = the Land 
Blue     BS No. 0-012 = the Adjoining Sea 
Yellow  BS No. 0-002 = the Mineral Wealth
