Orange / Green / Purple %:

...you set the amount value of the basic colors.

Back color %:

...This is the ratio for the back color as the grains shouldn't cover 100% of the picture, usualy 3%. This uses the primary color.

Color Variation:

...you could add a random variation to the basic colors to make it less regular.

Merge with image:

...This mixes the noise with the image if the color of autochrome and the color of the image are "similar", other pixels are turned to grey scale.

red <--> orange, green <--> green, blue <--> purple

Mask Orange-Green-Purple:

...If checked the image is replaced by the basic colors where the color of autochrome and the color of the image are "similar".

Duration:

...This is a slider to make the basic colors remain stable in horizontal lines.

Effect Mix:

...This is a slider to mix the final image with the orignal image to make the effect more or less subtile.
