<P> The Bhutanese subsequently redesigned their flag to match the measurements of the flag of India, which they believed fluttered better than their own . Other modifications such as changing the red background color to orange led to the current design, in use since 1969 . The National Assembly of Bhutan codified a code of conduct in 1972 to formalize the flag's design and establish protocol regarding acceptable flag sizes and conditions for flying the flag . </P> <P> Historically Bhutan is known by numerous names, but the Bhutanese call the country Druk after the name of the Bhutanese thunder dragon . This tradition dates to 1189 when Tsangpa Gyare Yeshe Dorje, founder of the Drukpa lineage of Tibetan Buddhism, was in Phoankar (Tibet) where he reportedly witnessed the Namgyiphu valley glowing with rainbow and light . Considering this an auspicious sign, he entered the valley to choose a site for the construction of a monastery, whereupon he heard three peals of thunder--a sound produced by the druk (dragon) according to popular Bhutanese belief . The monastery that Tsangpa Gyare built that year was named Druk Sewa Jangchubling, and his school of teaching became known as Druk . The Druk school later split into three lineages . One of these three, Drukpa, was founded by Tsangpa Gyare's nephew and spiritual heir Önrey Dharma Sengye and afterward spread throughout Bhutan . The nation itself would also later become known as Druk . This legend offers one explanation for how the symbolism of the dragon came to form the basis of the national flag of Bhutan . An alternative hypothesis maintains that the notion of symbolizing sovereign and state in the form of a dragon emerged in neighboring China and was adopted by the rulers of Bhutan as a symbol of royalty in the early 20th century . </P> <P> The current flag is divided diagonally from the lower hoist - side corner, with the upper triangle yellow and the lower triangle orange . Centred along the dividing line is a large black and white dragon facing away from the hoist side . The dragon is holding a norbu, or jewel, in each of its claws . The background colours of the flag, yellow and orange, are identified as Pantone 116 and 165 respectively . Equivalents of these shades and the white of the Druk are specified by various other codes according to particular matching systems as indicated below . </P> <Table> <Tr> <Th> Color scheme </Th> <Th_colspan="2"> Yellow </Th> <Th_colspan="2"> Orange </Th> <Th_colspan="2"> White </Th> </Tr> <Tr> <Td> RAL </Td> <Td> </Td> <Td> RAL 9000 Yellow </Td> <Td> </Td> <Td> RAL 3000 Orange </Td> <Td> </Td> <Td> RAL 1000 White </Td> </Tr> <Tr> <Td> CMYK </Td> <Td> 0.15. 94.0 </Td> <Td> 0.60. 100.0 </Td> <Td> 0.0. 0.0 </Td> </Tr> <Tr> <Td> Pantone </Td> <Td> 116 </Td> <Td> 165 </Td> <Td> n / a (white) </Td> </Tr> <Tr> <Td> HTML Hexadecimals </Td> <Td> #FFCC33 </Td> <Td> #FF4E12 </Td> <Td> #FFFFFF </Td> </Tr> <Tr> <Td> HTML Decimals </Td> <Td> 255.213. 32 </Td> <Td> 255.78. 18 </Td> <Td> 255.255. 255 </Td> </Tr> </Table>
