chromakey.sh RRGGBB X
RRGGBB = 24-bit RGB hex color value
X = the tolerance level around the color to key out
X can be any value from 1 to 16. The Chromakey Content will determine how wide the tolerance needs to be.
X = 1 will show only the RGB color specified.
Higher values of X widen the color range of the Key Region
