Yellow Rose

Yellow Rose is the het ship between Summer Rose and Taiyang Xiao Long from the RWBY fandom.

Canon
It was revealed in volume 2 of RWBY by Yang, that Summer was Taiyang's second wife. After his first wife Raven abandoned him and Yang, Summer came to help him raise Yang. During this time, it's assumed that him and Summer fell in love and eventually got married and had Ruby. After she left to go on a mission and was never seen again, it was presumed that she was deceased. This left Taiyang heartbroken and Yang then went on to say that he just kind of "shut down".

It was then revealed by Qrow in volume 3 that him, Raven, Taiyang and Summer all used to be apart of team called team STRQ. Summer was the leader of said group. Although we know little to nothing about team STRQ during their prime, it was heavily implied that Summer and Tai were close friends in the team. The two also raised Yang together after Raven left. Yang grew to admire Summer so much that she even eventually started referring to her as "Mom".

The fact that Tai never speaks about Summer might indicate that he's still not over her death. It might still be too painful for him to speak about. After his breakdown of her death it can be implied that he loved and cared for Summer very much. He then continued raising the girls on his own in her honor. It also is implied that Tai was aware of silver eyed people and never told Ruby about it, fearing that the same fate that befell Summer would befall upon her as well.

Fanon
Yellow Rose is a semi-popular couple in the RWBY fandom since they were one of the few canon couples in RWBY. Even though they have yet to be seen on screen together, they were married and had a child together. Some infer that the two were best friends before they eventually fell in love. Some have suggested that during their time at Beacon, the two had a similar relationship to that of Ruby and Jaune. They have a small fanbase on tumblr. They are both still the only members of team STRQ whose weapons and semblances have still never been revealed yet.
