Yes it's a food additive. It is used as an antioxidant and it is a color retention agent.
Movies use additive color, also known as RGB color. Colored light is projected onto a screen, so the end visual is reflective, but the color is additive RGB.
The additive color process is mixing lights while the subtractive color process is mixing paints and dyes. In the additive color process when you mix all of the main colors together: red, green, and blue: you get white(hence the name additive) while if you do the exact same thing in the subtractive color process: cyan, magenta, and yellow: you get black(hence the name subtractive because in order to get white you'd have to take away all of the colors).

On the additive color wheel, the opposite of Orange would be Blue.
The blue color comes from an additive that keeps evaporated salt free flowing. Normally this food grade additive would appear colorless to yellow. When the substance comes in contact with iron sulfate or dissolved iron in some hard waters, it turns blue. Not all pellets contain this additive and thus do not change color.
In the Philippines, sibukaw is utilized as a coloring material for the native fabrics. It is also used to color the coconut wine locally known as "lambanog" in Luzon or "bahal" in the Visayas. Some Filipino farmers color their fishing nets with sibukaw but this material was used as a colorant as pure sibukaw. To use sibukaw as a color additive will call for an experiment.
Red blue and green are additive.......so when we mix all three color we get white color
Yes, it is a primary color, but also a secondary color.
