This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for displaying image frames. A smoothing process can be utilized for mitigating image artifacts similar to dynamic false contouring (DFC). In some implementations, were a display to transition from an field specific contributing color (FSCC) having only two component colors to a target FSCC with meaningful intensities of all three component colors, or vice versa, and that target FSCC remained constant over a series of image frames, DFC-like artifacts would be mitigated at the transition by gradually, over a first number of image frames in a series of image frames, reducing the intensities of all component colors of the FSCC to values at or near zero, before gradually increasing the intensities of the component colors included in the target FSCC to their final target values over a remainder of image frames in the series of image frames.
