Tony, There are filters that you can aquire to filter colorbands...It
depends how sensitive your project is.
eg. Some color filters will let for example yellow through but infrared,uv
and other more extreme wavelengths will still pass through...If this is no
problem for the application at hand then l suggest looking in the RS
Catalogue as l think l can remember seeing something there.  If not decent
camera supply outlets may be able to help.
Cheers!
