A method for setting caption window attributes and an associated television system are concerned. The method includes steps of providing a plurality of attributive bit sets corresponding to a plurality of pixels in a caption; utilizing a window condition to compare the plurality of attributive bit sets in response to a setting caption window attribute command for changing window color to a destination color-change value, so as to selectively update partial bits of the attributive bit sets in response to the window condition; and displaying colors of the pixels according to the attributive bit sets and a palette, thereby changing the color of the caption window.
