Interestingly, it is permissible to use less than the 256-colormaximum in an 8-bit indexed color image. This is
often done to reduce further the imagery’s data footprint. For instance, an image that can attain good results using
only 32 colors is actually a 5-bit image and would technically be called a PNG5, even though the format itself is
generally called PNG8 for the indexed color usage level.
I have set this indexed color PNG image, shown in Figure 5-4, to use 5-bit color (32 color, or PNG5) to illustrate
this dithering effect clearly. As you can see in the image preview area, on the left-hand side of the figure, the dithering
algorithm makes dot patterns between adjacent colors to create additional colors.
