A listing, with manufacturer and name, of each
gel used on a
plot. With four major manufacturers each making over 100 colors, a list of only the colors used makes life easier for the
Master Electrician or for whomever is doing the take-offs and avoids confusion between the brands.
The Color
Call is usually placed near the Key on the plot. Sometimes the following is inserted into the Notes section instead/as well:
Color Media:
All "R" (or "RX") prefixes indicate
Roscolux.
All "L" prefixes indicate
Lee Filters.
All "G" prefixes indicate
GamColor.
All "AP" (or "A") prefixes indicate
ApolloGel.
The Color Call differs from a
Color Key, in that the former is only a list, whereas the latter includes a representation of angle, and may not include every color.
