When Lan Wangji sees red, he doesn’t think of blood, violence, and anger. No, when he sees red there’s only one thing, or more appropriately one person he thinks of.
Wei Wuxian.
When Lan Wangji sees red, he sees the way the ribbon in Wei Wuxian’s hair flutters in the breeze. He sees the way Wei Wuxian adds an excess of chilli powder to his congee. He sees the way Wei Wuxian’s cheeks fill with colour when he’s praised. He sees the way Wei Wuxian’s faded Wen brand scar comes back to life in a hot bath. He sees the way his husband’s red robes flurry about while dancing at their wedding. He sees the way Wei Wuxian’s lips are after Lan Wangji has thoroughly wrecked him.
Lan Wangji thinks, in his completely unbiased opinion, red is brilliant.
