Duplicate this layer. To make his face white, we will do
the same step as the arms. Select his face with the magnetic
lasso. Desaturate it, and then go to image, adjustments,
variations. Theres no need to click on "lighten" as it
remembered your last setting. Just click "ok" when it opens.
The face should be white now.
I just used a small brush and drew the outlines on his
mouth, nose, and eyes. I then selected these areas, and
copied them. This copied the selected areas of his white
face. I then pasted it on another layer. I went to Image,
Adjustments, hue and saturation. Hit the "colorize" box and
filled the selection with these numbers.

If you have more than one layer, go ahead and flatten the
image.
For the last step, the hair needs to be colored. This is
easy. Select and copy his hair, paste it on a new layer.
Again, go to Image, Adjustments, Hue/Saturation, and use the
same color as the arms. Then erase around the hair, erasing
the head and the background behind his hair.
To make McPeppers the Clown, I followed all these steps, but
first put Bpep's head on first. Much like a regular chop. Then I did
the steps mentioned in this tutorial.

There you go. Have fun!
