Food dyes? I thought those were what I got on my tie after eating spaghetti! The food that produced the blue of the sky didn't quite make it, but the food that produced the greens and browns of grass and earth did well, they are quite natural. I think you must have left the snow alone, though. That really does look good. Overall, it does capture that thin, wintry air with snow on its breath... Very evocative. Not appealing to the Velvia crowd, I guess, but vergy good with the image in this case. I'd say the experiment was a resounding success!
