Colorama START composition.
Using the Output Cycle
Let's now get a little more familiar with the Output Cycle
properties. No matter how deep or shallow your knowledge of
Colorama, you should know at least the basic features of this
function. The Output Cycle controls specify the color being out-
put from Colorama. This is the area that I referred to earlier as
containing a wealth of presets to use.
Go to the Mt Rainer comp. This comp contains a nested com-
position of a solid with the Ramp effect applied. I had to pre-
compose it so that Colorama would recognize the gradient. Now,
apply Colorama to this linear gradient and you'll see the now
familiar over-the-top rainbow colors that have been added to it.
In the Effect Controls panel, open the Output Cycle controls area
to view the actual output cycle. If you're just reading this topic
and don't have After Effects in front of you, you can refer back to
Fig. 6.37 to see the colorful output cycle.
The triangles on the output cycle are like color stops on a gra-
dient. This gradient is then mapped to the values in the layer. The
top of the output cycle (red in this case) is currently mapped to
red. And then, following the cycle clockwise, shadow areas are
remapped to orange, and 50% gray (the shade of gray exactly
between pure white and pure black) is at the bottom of the out-
put cycle (cyan in this case). The highlights are remapped to
magenta, until you come back to the top of the gradient, which
is also where white is remapped. That is why the black to white
gradient you see in Fig. 6.38 was remapped to red both at the top
(black) and at the bottom (white) of the layer in Fig. 6.39.
The triangles on this output cycle wheel can be moved around
to remap colors to different parts of an image. You can click in a
