[orange snow] the question is - why orange

We’ve something you haven’t, nyah, nyah, nyah! Our snow is orange and yours is just boring old white:

"A chemical test unit will be sent to Omsk ... it's main task will be to investigate pollution in the region and establish the degree of danger represented by the anomalous snow fall," the ITAR-TASS quoted an unnamed official from the ministry as saying. "Residents are advised not to use snow for their household or technical needs and to limit walking, either by people or their pets, in this area."

Snow ranging in colour from light yellow to orange and carrying a distinctive "musty" odour was observed yesterday in five districts of Omsk province, which lies in western Siberia and borders Kazakhstan.
