Using tungsten film in daylight will produce a bluish cast in the photograph. These filters correspond to the Wratten Series 85. The 85 series will produce natural colors when shooting with tungsten film outdoors. A #85 filter will decrease the color temperature from 5500K to 3400K and produce slightly cooler results than an 85B.
To get an accurate balancing of the light source to your film you can use the Mired System to calculate which filter or combination of filters you need to get "perfect color". Lionel Armstrong has made up a handy chart to explain The Finer Points of Color Correction
NOTE: Whereas the 85 series is used for tungsten film under daylight conditions, use the 80 series of filters (Blue) when using daylight film under tungsten lighting.
85 SERIES COLOR CONVERSION CHART
The # 85 decreases the color temperature from 5500-3400 degrees Kelvin
An 029 (85A) decreases the color temperature from 5500-3100 degrees Kelvin
An 030 (85B) decreases the color temperature from 5500-3200 degrees Kelvin
An 031 (85C) decreases the color temperature from 5500-3800 degrees Kelvin
