No, Wickham is the white one , His blood ran away from fear and embarrassment to see Darcy.Darcy is the red face of course from anger b/c he wouldn't like to see his beloved Lizzy whom he is trying to avoid and fears his being in love with, to be standing with him.

And BTW/ either Bingley noticed the cold manner of (Darcy's/Bingley's) greeting or not ,I think for sure Darcy and the Bingley's had a talk about Wichham ,either to explain why he was upset at that moment if Bingley noticed or to warn them from him and his company.And we have to remember what Charoline mensioned to Lizzy in Netherfields ball about how Darcy hates Whickham.
