My gs500s colors are bright pink and i tried changing white balance and nothing works

Try going into "reset" master mode. otherwise you need to make sure your camera is shooting on the right setting for the light you are using. For example, when shooting in daylight with interior light setting (approx. 3200k) your photos will look off color and yellow or pink because sunlight is 5600k approx.,. . . contrary while shooting indoors with incandescant lighting if the camera is set for sunlight exposure (5600k) the picture will look blue. Make sure you read the manual on how to white balace, but first take the camera out of AutoExposure settings to do all the settings manually. Auto focus and auto exposure are for rookies and these types of errors will happen. Always try to do manual iris and manual focus for best results zoom in and get your focus on the subjects eyes then zoom out and frame up your shot.
