I'm confused. There is no video and all of the note links are green on that page. Aren't yours?
I think what Adjusting meant to say is that "Copy note link" ought to give you a green link (internal one) and "Share>Copy Share URL to Clipboard" will give you a blue link. If this is not happening, could you post a screenshot of a note with these odd links in it? Thanks!
On that blog post they are all green, but the internal note links in my Evernote are blue when I select "copy note link". The only way I get the green links is by using the drag and drop method that you recommended (which is a good tip, thank you!) I can file a bug report for the blue links I keep getting
Either way, I'd still love to be able to change the color of external links to something else. Wish there was more demand for it, it seems like I'm the only one
Please do file a support ticket. A screenshot would also be nice
As for note color links, I don't think there is very much demand for it. Sorry. However, I (and others) have a long-standing suggestion that would address your issue -- style sheets. We would like to be able to have user defined styles for our notes. If we gained this ability, you could change note links if you'd like. Any number of other apps on iOS and OSX give you this kind of control (note links included), so I think this is a fairly widespread feature request, even if people don't focus specifically on asking for different link colors.
In a word: customizability.
