I think in the DiCaprio/Winslet version of Titanic he is so dutiful saving Winslet that she has the pleasure of watching him fade to blue. Maybe it was someone else that I remember turning blue, but as he is in the water and she is watching him, he is a likely candidate. In the back of her mind she may be thinking "What a beaner not to know to save himself, first." She may have been afraid that he would reverse his heroism, unseat her and chuck her in the water. We'll never know.
While DiCaprio is busy being the Bodhisattva of the iceberg's Atlantic, the captain thinks "Oh, shit," knowing the ship is going to hit the 'berg. Meanwhile DiCaprio, dying, is exalted by the bodhichitta from foregoing life and dropping self.
The captain despairs that cost cut the number of lifeboats to few. Beset by the onset of his tarnished reputation, he wanders from the public bridge and drowns in private.
