Natural Red is just like the Crayon/marker color , natural blue is like the crayon/marker color,and natural green is like the crayon/marker color. So take a White Paper and draw 3 separate lines with the Red, Blue, and Green with the crayon/markers. So when you use a calibrate system/disc for your T.V. look at the paper and try to make the colors look as close as possible to the colors on the paper without washing out the colors.
if you really want to get fancy,
and more professional.
used a test disc/test image.
or match it against pantone colors
with a colorimeter:
