I don’t see much problem with the brass and spring setup. You don’t want a sharp point sticking up reducing spring contact. If the solder is sticking up you can run an iron over the top to level it out. Be careful not to unsolder the wire.
I’ve seen you use Google and Flickr. I prefer Imgur. Did you try that?
There was no story at the place you found the picture?
They probably had a sample made of every color their anodization company could do to figure out which looked best to offer for sale. They obviously can’t offer every color, they’re already starting to reduce the options, so they have to narrow it down somehow. That’s my guess.
Well… i believe i can tell some colors… The finish that was pointed out does not look red to me either, more like squashed red fruit like raspberry indeed. However, for what i’ve seen of some ‘red’ lights, they did have some purple in them… Considering lighting conditions and white balance. So yes it could be it.
