<P>Still and all, there aren&rsquo;t all that many uses for basic color compare operations. There is, however, a genuinely odd application of read mode 1 that&rsquo;s worth knowing about; but in order to understand that, we must first look at the &ldquo;don&rsquo;t care&rdquo; aspect of color compare operation.
</P>
<P>As described earlier, during read mode 1 reads the color stored in the Color Compare register is compared to each of the 8 pixels at a given address in VGA memory. But&mdash;and it&rsquo;s a big but&mdash;any plane for which the corresponding bit in the Color Don&rsquo;t Care register is a 0 is always considered a color compare match, regardless of the values of that plane&rsquo;s bits in the pixels and in the Color Compare register.</P>
