大概是你喜欢红色而我姓黄
[dà gài shì nĭ xĭ huān hóng sè ér wŏ xìng huáng]
'Probably it's because you love red while I belong to Huang' (a common Chinese surname often phonetically spelled Wong, Hwang) indicates that the color difference here might represent an unrequited love due to unsuitable matches, either in personalities or social standings.
