The only one I have with red hair is 621iii (Medium Fluorescent) position 21. The red is not as vivid as wert's 621 (unknown florescence) position 17 or Pollux's 621ii (Fluorescent) position 24.
My scan is great, but is terrible once I upload here and I've redone everything several times.

Pollux's position 25 has red in the background to the right of her head.

This is not mine and of a unknown position.

As there at least two different fluorescent varieties (F and MF) and three different positions, it is doubtful that there are constant varieties of the transient reds.
