I'd consider what color is blocked and what is passed through the filter, then work with the luminance to get the effect. So, yes...a red filter would block blue and some green.

They're both very nice.  You might try reducing the green luminance some to

This gives me an idea.  What if I want to see what the picture would look like 
had I shot it through a red filter.  How would I do that?  Just drop the green 
and blue luminance? Twiddle with camera calibration sliders?  Is there a better 
way?
