sparkplugs question- ?

[geomeo]

Can someone take a look at my mini coop sparkplugs and tell me if they are ok? I'm having a job finding images on google that look like them. There's a slight hint of orange on them which appears to look normal, but I'm not sure. I'm also not sure how this insert images work as it asks for a URL. www.gphone2.net (http://www.gphone2.net) is where I've posted them.

Many thanks for your help in advance.

There is quiet a bit of carbon build up on the prongs. I'd think strongly about replacing them.
