Anyone given Color Daguerreotypes a try?

>From the back of an old Daguerreotype manual:

COLORED DAGUERREOTYPES ON COPPER.--To effect this, take a polished plate of
copper and expose it to the vapor of iodine, or bromine, or the two
substances combined; or either of them in combination with chlorine. This
gives a sensitive coating to the surface of the plate, which may then be
submitted to the action of light in the camera. After remaining a sufficient
time in the camera, the plate is taken out and exposed to the vapor of
sulphuretted hydrogen. This vapor produces various colors on the plate,
according to the intensity with which the light has acted on the different
parts; consequently a colored photographic picture is obtained. No further
process is necessary as exposure to light does not effect the picture.
By this process we have an advantage over the silvered plate, both in
economy, and in the production of the picture in colors.

Anyone give it a go? What colors, exactly? Doesn't sound like the color
process that someone else was trying to perfect at the time, and it most
CERTAINLY isn't the Polaroid answer to the color problem.

It _is_ interesting, though.
