type that is one color when viewed from one angle, and a different color
when the angle is changed. And I have some questions about it before I
decide.
1. I have only seen this on certain bikes
(Cannondale?). is it a patented
process, therefore unavailable to the
general public? If not;
2. How expensive?
3. Can it be done "at home"? Assuming
one has the proper equipment
(compressor, paint gun). How complex
is the process, and where could I learn
how?
4. What color combinations are available?
I would like something like green/cyan.
Again, TIA

I can't imagine a custom painter not being able to do this. Or an auto
paint place should be able to provide it. At my work, we have these
types of pigments. They either come from the manufacturer mixed in a
base (e.g. Beckers from Sweden) or in dry powders that we add to a
clear medium.
The base color is critical for the effect, as with most metal flakes.
And the thickness of the coat is also important. Getting a consistent
thickness, within 1/1000" or less, can be difficult on bike tubes.
I've used a little of the powder among other pigments in one bike
paint job. The flop is minimal and subtle. I applied a urethane top
coat- ChromaClear 7600 (two part, dangerous for home use) which didn't
seem to have a huge effect on the flop. Beckers provides it own top
coat which is pretty matt, but I have no idea how this would hold up
on a bike. I'm going to test it soon for an upcoming paint job.
Basically, either have a bike painter do it- should be very possible.
Or talk to an auto paint supplier. Get a good respirator- forced air
preferable- and be careful. Some serious chemicals in some of these
paints, and metal powder is never good for the lungs.
Be careful with these pigments- they can be eye striking but actually
quite ugly. As a guy I worked with said, it looks like a couple of the
colors you get in the bottom of the dump bucket when mixing paints.
Choose carefully and judge it in sunlight.
