[3] Shankar Nath Rimal, a civil engineer, standardised the symbol on the request of King Mahendra.[4] It borrows from the original, traditional design,[5] used throughout the 19th and 20th centuries, and is a combination of the two individual pennons used by rival branches of the ruling dynasty.A 1928 French book about Nepal shows a double pennant flag with a green border rather than the modern blue.The constitution dedicated an entire section to the precise size and shape of the flag, since people were drawing it incorrectly.[citation needed] In May 2008 during the drafting of the new constitution, various political parties demanded changes to the flag's design since it symbolized Hinduism and monarchy,[12][13] but this proposal was rejected.The crimson red indicates the bravery of Nepali people (and is the country's national color) and the blue border represents peace and harmony.[10] A precise geometrical description of the Nepalese national flag was specified in Article 5, Schedule 1 of the former constitution of the Kingdom of Nepal, adopted on 9 November 1990.[17] The large-scale production of the Nepal flag is difficult because of its exact proportions and it is normal for it to be completely out of shape during large events.[22] During a 2018 visit of the Indian Prime Minister Narendra Modi to Janakpur, a version of the flag with incorrect shape and geometrical proportions was flown by officials, causing outrage on social media and with national personnel.
