Colours - stucky x male oc

Soulmate Au
Bucky and Steve had never been able to see the colour blue. Ever since they figured out they still had a missing soulmate somewhere they couldn't stop looking. They missed and longed for someone they had never met. But after being reunited they begin to lose hope that they will ever see their soulmate since they could be old and on their deathbed.

Nico Rivers had only ever seen the colour blue. He didn't know if he should hate it or love it. Most soulmates could not see any colours before meeting their soulmates and Cole had laid awake many nights thinking of what that could mean for his soulmate bond. Then Tony Stark finds his little house near the woods.
