Some notes about film color, value, saturation, and hue, as might apply to my own work


Back in the 1998-2003 period when I was living in Minneapolis, IFPMSP held many forums on filmmaking technology, including film stock.

I wanted to give a few links about concepts regarding image color and focus, because they would become relevant to filming my “Do Ask, Do Tell: Epiphany”.

Of course, people pay tuition and get degrees from film schools to learn these things.

Leighcotnoir has some valuable links.

Look at this explanation of hue, saturation, and value, particularly the 3-D cone near the bottom of the page that gives an example based on “red”.

It’s also important to study the concept of “primary colors”, as explained here, along with color wheels.  Note how primary “additive” colors (red, green, blue) work, where as “subtractive pigments” (Yellow, magenta, cyan) work in tandem, because when paints are mixed, the light wavelengths that may be reflected are “subtracted”.

There is also the “hue-saturation grayscale”, as explained here.

And “Filmschoolonline”  explains the “attributes of the visual image”, including Brightness, Contrast,  Quality of Light, Focus, perspective.  Here, color is explained in terms of saturation, hue, and emphasis.

There is also the opportunity for 3-D without glasses, “autostereoscopy“, a kind of holography, as explained in Sciecemag,


I do want to discuss the color scheme for the “flashbacks” or “backstories” of my Epiphany screenplay.


The Final Draft document shows several color modes:

White — Black and white presentation (the embedded screenplay “The Sub”).

Blue — scenes at ashram, in mild color-blindness called green-weak deuteranomaly  (see a color blindness “simulator“).

Red — backstories in full color as they would appear in nature  (moderate value and saturation)

Orange– backstories known to and told by characters other than Bill, higher saturation.

Green — historical narrative told to characters other than Bill (higher value)

Purple — immediate, quick flashbacks (higher value and saturation)

Yellow — acted historical narrative (treat as red)

Gray — historical relative to “Sub” screenplay, black and white

Some directors change aspect ratio for different kinds of backstory.  I think this creates problems, because different theaters handle cropping different (in many auditoriums, 2.35:1 is accomplished by vertical cropping, so presenting some backstories in smaller aspect can require more cropping). I would prefer 2.35:1 for all scenes, but use different color schemes.

Much of the action takes place in an “ashram” which is envisioned as the inner surface of most of a cylinder mounted near the space station on Titan, about 2 miles in diameter and 10 miles long, rotation for artificial gravity, that  is, a “rama”.

I’ve talked about Clarke’s novel here before, but it seems that there have been few movies about societies of people raising generations while on an evacuation ark (like “Evacuate Earth“).  These situations certainly could explore the idea of “social capital”.
