The Long Āgama Sūtra 2.63

2.63

時，毘舍離諸隷車輩，聞佛在菴婆婆梨園中止住，即便嚴駕五色寶車，或乘青車青馬，衣、蓋、幢幡、官屬皆青，五色車馬，皆亦如是。時，五百隷車服色盡同，欲往詣佛，菴婆婆梨辭佛還家，中路逢諸隷車。時，車行𩣺疾，與彼寶車共相鈎撥，損折幢蓋而不避道，隷車責曰：「汝恃何勢，行不避道，衝撥我車，損折麾葢？」

There was a group of Licchavi men who heard that the Buddha was going to stay at Āmrapālī’s Park. They had five-colored precious chariots and horses. Some rode on blue chariots with blue horses, and their clothes, parasols, banners, and retainers were all blue. The same was true for the other four colors, too.

500 of these Licchavis dressed in entirely in the same color decided to visit the Buddha. Āmrapālī was returning home after speaking with him and encountered those Licchavi chariots on the road. They were traveling very fast and collided with each other. Their banners and parasols were knocked down, but she didn’t move out of their path. The Licchavis yelled at her, “Who do you think you are, not making way for us? You’ve run into our chariots and knocked down our banners and parasols!”
