Jadeite features many colors. Sculptors generally cut away everything other than the imperial green, which is the most eye-catching and expensive part, but Hu likes to incorporate all the different colors into his work, making them into different types of fauna and flora. He is especially fond of using the contrast between two different colors to highlight the design of the work and achieve a rich depth of composition.
翡翠雖然多彩，然而當做商品買賣時，雕刻師總會儘量切除其他顏色，單單保留最耀眼也最昂貴的翠綠；在胡焱榮眼中，色澤變幻無端的翡翠卻恰好可用於雕作各類動植物題材，尤其運用兩色相接、濃淡漸層的變化，更能巧妙地彰顯佈局與構圖豐富的層次感。
