I don't have any pics, but from what I remember seeing both colors in person, pink ruby is a vibrant hot pink compared to the deeper, more purplish tone of cranberry. I think they're fairly different - personally I would use pink ruby in summer and cranberry in fall.
Here's my cranberry phoebe next to pink ruby Georgie. They're very different.

Wow. Now I want cranberry phoebe
Cranberry is almost exactly the same color as magenta Isabelle. Pink ruby is more hot pink.
