Radiant of meteors

Some parameters have to match with such photo actions. A clear night sky, new moon and the Perseids almost give this meteor cocktail shown below by showing a radiant. This means that all the meteors appear to come from one point. This point is located in the constellation Perseus, from where the meteor shower is named. Unfortunately often times stubborn peak clouds joined the clear night sky, hence we had only 2 hours time to take pictures. Hardly imagine if we had all night to snap. Nevertheless a passable radiant succeeded at the summit of the Geister-Spitze at 3465m. Below in the foreground the mountain Ortler with its 3905m.

 Tamron 17mm (~27 dig) f 2.8, 30 sec , ASA 400, Canon 20D

This photos were taken near Donauwörth. Significant is the green entrance color which is changing into red.

After an inquiry at the working group Meteore e.V. the following information from Mr. Roland Winkler was given.

The colored impression results  in any case from reciprocal effect of meteorite material with the upper atmosphere layers. Deceleration speed and temperature plays a rather subordinated role. A member of our association (working group Meteore e.V.) had put on a statistics over some years ago in order to the meteor colors, which brought however no reference to your statement above ( snief!! ). Usually Meteors are visually observed usually from the white color, perhaps with a weak bluish inside. With the appearance of bolides sometimes different colors can be observed.
