And even if we provide a handmade print on the best paper with the best quality ink we still have no control over the viewing environment.

Because this can sometimes be tight, GIFs have the option to dither, and will mix pixels of two different available colours to create a suggestion of another colour. As all recent browsers now support the PNG format, it is time to abandon GIF for most purposes. The PNG of the above image is smaller than the GIF, and PNG is not limited to 256 colors as is GIF.
