Can pinhole camera be used on colour film, I suspect yes, why not.

But just want to check if it is worthwhile.
 
Funnily enough I was pin holing today, using my Chroma Cube - a 35mm pinhole camera. I've had a roll of HP5 in it for ages but I want to get it finished so I was shooting it off at various calculated manual shutter speeds as a test.
I can't see why colour would not work, in fact it would be interesting to see the results.

That's interesting Lindsay, I hope that your kind enough to share your calculations and subsequent results when they are available.

I also think colour film might be interesting, potentially there could be some excellent diffraction, due to the very long exposures, in the different emulsion layers.

Yes, colour 120 film, Fujifilm Pro 400H IIRC

That's brilliant. I am going to make one for that size film!.

Did you attache a roller mechanism or cut it up into sections?
 
Here's some examples of 35mm pinhole images shot on colour film:

35mm pinhole with a Fed 4

In the past I have thought that 35mm was just too small a format to be useful for pinhole photography. Surely the images would be just too soft or rough for my liking? However I did see some exampl…

and a medium format colour pinhole image:

I prefer colour pinhole shots for the impressionistic, conceptual effects. All pictures taken with home made cameras adapted from 6x9 folders.

First home made camera with pinhole made from a bit of beer can with a hole punched in it with a needle. Dea good diffraction effect.

Second camera made from an Ensign body with a laser drilled pinhole.

Really good for capturing movement.

The second shot Peter shows exactly what I speculated would occur, the individual colours are fine but white really burns through that thick emulsion and the diffusion there is great,

I reckon that you could possibly get some fantastic shots with the right scene, ethereal and ghostly!

The Ensign has an actual focal length of 14mm, I discarded the bellows. Film Fujicolor Superior 100, expired 2006, of which I only have one remaining roll, very sad as I nailed the reciprocity correction from the film data sheet. The pinhole gives an aperture of f183, can't remember the pinhole size, maybe 0.3mm.

As you may have gathered I'm not expecting perfection from my pinhole cameras, if I want that I've got other options, i.e. cameras with lenses.

As far as I am aware light travels in straight lines, I think that there are a few cases when it has been seen in detailed astronomy images that light is occasionally bent due forces we are not 100% sure about (but I stand to be corrected there)

In a pinhole camera how does the light through a very small pinhole achieve a full image with a wider area of view that the hole will allow?

In the universe gravity can bend light so if you were to take a photo of a very distant star it not might be where it actually is.

Think about why the image is reversed and you'll get it.

I had to look it up but think I have got it.
Avoid writing in subject matter!

In my Astronomy days I often used to look at close together twin stars and thought that it was the same star but somehow the light from the star had been split giving an optical illusion of two stars. Black holes can bend light as well I believe.

..and light from a distant star takes so long to reach us it might not exist anymore e.g. exploded
 
Or, given that "time" is to some extent an artificial human construct, it may not exist yet...
 
I think, unless you buy into the weirder concepts of astrophysics, it must have existed for you to see it. ;)
 
Or it's an optical delusion (sic).
