Is there any substance in the "usually blue" claim?

@MartinArgerami The usually blue applies to the plug (not the cable) - "Since USB 2.0 and USB 3.0 ports may coexist on the same machine and they look similar, USB 3.0 specification mandates appropriate color-coding and recommends that the Standard-A USB 3.0 connector has a blue insert (Pantone 300C color). The same color-coding applies to the USB 3.0 Standard-A plug"

There's a semi-official colour scheme I've noticed with sockets - USB 3's blue, USB 2.0 charging connectors (which are powered even when the PC they are off) are sometimes yellow. I'd rather look at the connectors for identification since I have blue usb 2.0/1.1 cables.

I understand that it's a quote, but I think that “will fall back...” should really be “will not magically increase”.

For completeness, it's worth mentioning that 10GB USB3.1 ports (twice as fast as the 3.0 standard) are commonly a lighter shade of blue. I don't know if this is an official recommendation or not; but has held with most of the 3.1 board prototypes I've seen so far.
