PRIME EFFECTS OF COLOUR FILTERS ON YOUR
SIGHT PICTURE
If clarity of the black target bull is lost it can be sharpened by our colour filters. These optically flat
glass colours allow the passage of specific wavelenghts while restricting others - enhancing the
black against the white in varying degrees - dependant on the colour filter selected.
light grey: absorbs 50% of normal light
dark grey: absorbs 75% of normal light
brown: turns artificial light with a light bluish tinge into what appears as natural daylight
light blue: turns artificial light into natural light
dark blue: as above - used for brighter artificial light
red: enhances black and white contrast and reduces glare from the white surround
orange: effect of clarity is as above however orange also reduces interfering ambient light
yellow: effect is similar to that of orange but over a reduced wavelength (range of light)
lemon yellow: effects slightly higher wavelengths
light green: comfortable to the eye - effect as for orange
dark green: as above however for more powerful light
lilac: increases contrast in the red / green spectrum
