your links presents lights that are out of focus.
That "angelorbs" in your links thing are just reflecting light: it is not the same.
I happen to have a picture of my own of that, these are LED lights where I just zoomed them "out of focus":
You seem to not understand that with circles of confusion in optics it makes no difference whether the object out of focus is reflecting light or is generating light like an LED. It makes zero difference to the optical physics of the bokeh circle.
Can you tell us what you remember about phase change in water from high school?
I get the impression from your facebook page that you haven't grasped that when water evaporates it becomes water vapor.
Water vapor cannot evaporate because IT IS the evaporated state of water.
When a fog or mist disappears it disappears because it either blows away or it evaporates. Thus when it evaporates and disappears it BECOMES water vapor.
Water vapor is lighter than the other most common gasses in the atmosphere . ie, lighter than Nitrogen gas N2, lighter than Oxygen O2, lighter than Carbon dioxide CO2 . Therefore moist or "wet" air is lighter than dry air.
BTW your webpage shows a number of aerodynamic contrails which create an iridescent coloured effect due to mie scattering of light caused by growing ice crystals.

I've noticed references to colour in clouds on other chemtrail adherent pages and there seems to be a general idea that they must be because of "chemicals" because oil is thought of as an "un-natural" chemical and it forms colours sometimes (when a thin film of it floats on water ) .
I think the thought process goes "oil is a chemical.. I've seen oil produce rainbow colours , therefore chemicals produce rainbow colours .. therefore if I see rainbow colours its because of chemicals.."
Ironically , when oil is used deliberately to produce smoke as a fine aerosol it doesn't make colours.
(Skywriters and some types of aerobatic smoke use oil pumped into engine exhaust manifolds to make smoke.)
Interesting when people only familiar with the common colourful phenomenon of thin film interference from oil slicks on water try to attribute a phenomenon they don't understand anyway to everything that resembles it.
