What color is Jesus, and is there a Hadith contradiction?

In some hadith, Jesus is said to be of red or reddish-white. eg: > Narrated Ibn \`Abbas: The Prophet (ﷺ) said, "I saw Moses, Jesus and Abraham (on the night of my Ascension to the heavens). Jesus was of **red complexion**, curly hair and a broad chest [ [ref](http://sunnah.com/bukhari/60/109) ] Also see Jesus was **[reddish-white](http://sunnah.com/bukhari/92/75)** . Yet another hadith says: >Narrated Salim from his father: No, By Allah, the Prophet (ﷺ) **did not tell** that Jesus was of red complexion but said, "While I was asleep circumambulating the Ka`ba (in my dream), suddenly I saw a man of **brown complexion**. He was the son of Mary. [[ref](http://sunnah.com/bukhari/60/111)] Only Allah knows the truth, but my question is: why two sahih hadiths contradict each other or, why two contradicting hadith are graded as sahih?
