年毕业于北京师范学校，继入北京艺术专门学校国画系，受业于王梦白（云），陈衡恪（师曾）诸先生，毕业后被聘为北京师范学校及艺术专门学校国画教师，中国画学研究会评议委员。除讲课授徒之外，并观摹历代名迹，深谙古法，教学相长，于国画中之山水、人物、花鸟、走兽各有所长，尤精于花鸟，在潜心研究之基础上，听鸟说甚，问花笑谁，工笔写生，遂成大家。常谓“西画有人物、静物、翎毛诸种，形象真实，但只是标本画，而配景极少。或于风景画中偶然出现花鸟而已”。伯龙先生深知国画不同于西画，以已之所长，对花鸟画深究独创，为使郭画艺术弘扬于世界而尽自己之职责。(颜伯龙初时就读北平艺专，师从齐白石、陈半丁、陈师曾、王梦白等名师，为王梦白入室弟子。文学上师从林琴南。与李苦禅、汪慎生、王雪涛、邱石冥皆为同窗之友。颜伯龙早年绘画受王梦白影响，多拟新罗山人笔意，画风上多有八大、新罗之遗韵。中期逐渐摆脱前人风格，已在画作中融入一些自身的笔法，如在画作中多题“拟元人笔意”、“仿林良(吕纪)笔法”、“仿李复堂笔法”等。在不断拟古的过程中，逐渐做到兼收并蓄，集宋、元、明、清历代花鸟画法之大成，亦在不断融入自己的丹青意趣，终成一代花鸟大家，形成了颜氏“兼工代写”的独特花鸟画法。)
