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

i did that experiment in a closed room ther it doesnt change its colour when i went outside its changes its color.. wat the reason for changing the color

[Peggsy]

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.

[kishore1984]

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