RGB for blue screen compositing

[lostbythelake]

Hi there,

I'm new to the world of film making (obviously, hence my post in the newbies section), and I am wondering about building a screen for blue screen compositing.

I was planning on having a large matte finish pannel printed out that's just the right colour of blue. Problem is, I don't know what colour of blue I need. Do I need a true blue (i.e. RGB = 0, 0, 255)? And if so, what is the equivalent CMYK colour for printing.

This might seem like an obvious question, but again, I'm just one of those newbies.

Cheers :wink:
