For this photo, I used an on-camera circular polarizer. When I imported the image into Photoshop from Raw, I maxxed out tint and satuartion.
In post processing, I added color to the sky with a dark blue gradient filter. I added the color cast to the water with a user-defined split color filter (nik color Efex! Pro), and finally add the red cast in the lower-right quadrant (also from nik).
