In the "Misc" tab, you can specify how to treat grey colors. By default,
grey is not considered as a color. But all colors, when they are very
desaturated, look like grey, and you can tell filter to consider grey
as a very desaturated color which will be affected by rotation.
</p>
<p>
<span class="guilabel">What is Gray?</span>: You specify there how much saturation
will be considered grey. By increasing progressively saturation, you will
see an enlarging circle in color circle and enlarging selected areas in
Preview if Change To This option is checked.
</p>
<p>
<span class="guilabel">Hue</span> and <span class="guilabel">Saturation</span>: You set here
the color you want grey to be transformed to. You do that, either by entering
values into input boxes, or by click-dragging the small central circle in
Hue/Saturation circle.
</p>
<p>
<span class="guilabel">Mode</span>: With <span class="guilabel">Treat as this</span> option,
there will be no change in preview, selected "grey" areas will take the
selected color and a rotation will be performed on image. With

will be applied to "grey" areas and will appear in preview but no rotation
will be performed.
