I have the same problem: any green foliage (grass, bushes, tree canopy) looks pink on my WVC200. People look at it and ask me, "Why are my grass and trees pink?" I had linksys replace the original one but the second WVC20 also had the same problem.
I've had an open problem ticket since June about this. In July, after the second camera had the same problem, they finally passed it on to the "proper department" so they can follow through on it. I believe that means they tossed the incident into a black hole since I have never heard from them since and there have been no firmware updates.
And then sololink's server took a hit last month and my camera has not been online since then. The sololink forum indicates users are being told it is a known problem but nothing yet has been done about it. I finally cancelled my sololink device accounts and moved to DNDNS.COM. DYNDNS.COM actually works and its free.
I'm very disappointed with Cisco/Linksys customer service. They were once a top-notch company.
