For the teenage schoolboy the biggest thrill is the flaunting of the College Flag .At every school sports encounter the college flag is carried as a display of one's loyalty to the school .The young "smiling rascal" displaying the College Flags keeps up the College spirit .The earliest mentioning of the College Flag is at the Prize Giving .There is no record in any document of the college Flag prior to 1904.

In the colonial era, although the College colours exited, the union Jack had to be carried by the boys of Royal College in any March Past, as the empire Day Games. Not much flag waving is reported in the earliest period when cricket was introduced .In later years flags were seen sticking out of bullock carts, parading around on big Match days .Later on bicycles, still later on cars and finally from buses and even lorries. The College Flag is an essential item of students equipment of Royal-Thomian Cricket Match and even at the Royal-Trinity Rugby Match .Prior to the 1950's the College Flags were never carried to a Rugby match. In his Prize Day speech in 1924 Acting Principal Sampson said "as a part of the same scheme I have had the College Flag embroidered with the college Crest. I hope that the Flag will serve as a symbol of devotion owed by every Royalist past and present to his School. A school that is worth any thing must impress on its boys a sense of loyalty and devotion and I hope that this Flag will help to produce in all Royal College Boys a sense of loyalty to their College, keep their Flag flying as the proud symbol of the best school in Ceylon.
