"On the issue of icon color, there may be two different answers for two different groups. The first group is comprised mainly of people supplying feed-enabled applications (e.g., news aggregators, whether stand-alone or integrated into other apps) or operating equivalent online services (e.g., web-based aggregators). For these types of applications I think it's more important to have a standard color, to help orient new users.

"People just using the icon on their own web sites (e.g., bloggers and others)…are going to have more variation in web site color schemes, icon types, and so on; that's just a fact of life. [...] I think one can justify putting a lower priority on standardizing the icon color for web sites, and allowing more flexibility in icon color."

So I don't think we have much of a problem here.
