The green hue can only be due to coupling of cyan-coupler (something that only could be explained by red-light exposure) or by retention of a greenish dye.
In the latter case though that dye must have enough density to compete with the orange dye of the uncoupled couplers.
Unexposed film (eg. edges) must either be nearly colourless (unmasked films) or have a strong orange hue (masked films). This is due to the the inherent colour of the ingredients of the base or emulsion. A fault in temperature would have no effect on this.
