Ice Blue is my favorite Fender Custom color of all time. Years ago ReRanch.com didn't make it, so I begged Bill at ReRanch to mix me up the first batch ever. He sent me 2 cans for a project I was working on.
The first photo is too dark. The second photo is to bright blue. Ice Blue to me is a cross between the two photo you have. The first photo may be vintage, color has aged somewhat. While the later is a fresher paint job. But certainly most likely could just be lighting & angle of viewing, as well as aging.

Ice Blue Metallic (also called Blue Ice and Silver Blue by Dupont) Is a 1965, '66 Ford color and used by Fender from 1965 to '69. The color has a very fine metallic component but will change color dramatically depending on the viewing angle. Ice Blue is the quieter, and perhaps cooler, brother of Lake Placid Blue.
