why not do a small experiment, prepare it in the dark at room temp, see if the color change is still evident, maybe even try in the dark at a lower temp (say 4C) to check for temperature effects.

sounds like fun! if you do this, please report your observations back here

how did you prepare your solution, what grade are the reagents that were used?

This solution would seem to be quite stable from what i can find on the web (google and lit searches). I am unfamiliar with this solution, what is the exact color change that occurs? Nice challenge indeed.

the color is pale white in color first and changes to slight pink based on the light ....
