um, just a follow-up question.. the site mentions red, green, and blue as the additive primaries, and cyan, magenta, and yellow as subtractive primaries. but what happened to the ol' red blue and yellow? i'm thinking maybe it's the difference between paint and printers, or maybe i was just always told the simplified version?
probably a stupid question, thanks for any help tho...

When it comes to pigment, red, yellow, and blue are basically the same as magenta, yellow and cyan.
Here is a normal photo:
Here is the same photo with COLOR HALFTONE run on it in Photoshop. See how the benday dots are CMYK? That's because cyan, magenta, yellow, and black are the subtractive primaries.
Okay, now check this out:
First I roll the HUE on the picture -45 degrees to whack it out.
THEN I apply the color halftone. The whacked out picture turns into CMYK dots.
FINALLY I roll the image +45 degrees. Now the picture is UNWHACKED, but the halftone dots are now WHACKED OUT. Here it is:
Whether I use CMYK, or whacked out primaries you've never heard of, I still get the proper picture.
