2. Open the Channels Palette
The first thing you do, is to open yourChannels
palette.
Go to Window > Channels.
In the Channels palette menu you will see that
Yellow is the channel which has the most color for the star. So
drag the yellow channel thumbnail onto the New Channel icon at
the bottom of your Channels palette. A new channel called Yellow
Copy will appear in the Channels palette.
Now, don't worry if your graphics looks black and white, this
is because you are not viewing all of the channels that compose
your image, but only the Yellow Copy channel. Just click on the
CMYK thumbnail in order to see all of your colors again. Now that
you have an additional yellow channel though, your colors will
look different, but still don't worry, we have not finished yet. return
