The three-color channels the tool works on are listed separately, and the values for each can be
manually edited if you wish. That’s a tedious approach though, so all you really need to do is
right-click the color swatch provided, and either:

Click the spot in the image that is closest to white already.
or …

Keep pressing the mouse button as you glide around the image, and watch both the
color swatch and correction update in realtime as you do so – until you find a result you
are happy with.
The next section of the simple Color Correction group holds familiar tools:
Brightness – adjusts the luminance (lightness and darkness) of the video signal.
Contrast – adjusts the levels of gray in the signal (co-incidentally, also affects the brightness and
saturation of an image.)
Saturation – refers to the intensity of color in the video signal. Low saturated pictures look gray,
while overly saturated images show colors that bloom to the point of smearing.
Hue – adjusts the relative phase of color and works on the principle of a color wheel. As you
rotate the knob either way, you cycle through the colors. The functional range is between 0 and
360.
Gamma – part brightness and part contrast, when applied, Gamma can improve the contrast of
the mid-range of an image’s tones, without damaging either its lightest and darkest values. The
net result can be a more dynamic image, literally.
