The SX50HS camera has a creative color accent filter. To use this feature, turn the shooting mode wheel on top of the camera until the white mark aligns with the Filters setting. Then select the filter by pressing the left or right of the back central button until it displays Color Accent filter. Press the FUNC SET button. Press the shutter button to be in shooting mode. Then select a color to highlight or accent by pressing the DISP button. Once you pinpoint the color in the scene to highlight, press again the DISP button. then take the shot of the final scene. Practice until you get the hang of it. Here are two sample photos.
The two photos above have different color accents. I selected a somewhat yellowish color and a reddish color in the first and second photos respectively.
