While the selected color vector is displayed in a light grey, the colors not
selected are shown in a darker grey. The blue-grey surrounding the vec-
tor marks the softness/tolerance of the selected color vector, i.e. the
colors lying in this area will be selected as well, but a color correction
will only be performed on them on a percentage basis. This percentage
basis is calculated from their distance from the selected color vector,
meaning, when a value is near the selected color vector, almost all pix-
els of this color will be selected (close to 100 %), while colors at its out-
er edge are barely selected (close to 0 %).
The color vector and softness can be changed either with the preview
window by selecting colors via the pipette directly or with the bars, slid-
ers and entry fields to the right of the color wheel. Additionally, the col-
or mask in the color wheel can be selected with the mouse and moved
to another position in the color wheel. This way not only the hue of the
color mask can be adjusted but its saturation as well.
The Bars and Entry Fields
With the bars and entry fields you can change the color vector shown
in the color wheel and visible in the alpha mask of the preview window.
Figure 7-40: Bars (left) and entry fields (right)
The bars show you the exact values of the color vector displayed in the
color wheel. Each bar provides either a trapezoid or a rectangle (yellow
lines, in the following called ’selection shapes’) that mark the respective
hue, saturation or luminance currently selected. The settings of the se-
lection shapes’ corner points can be seen in the entry fields to the right.
The left two corner points of the selection shapes select the vector,
while the right two corner points of each mark the softness of the set-
