Having the same problem over here, wanted to use an external link to each image.
This used to be possible with custom fields, adding them to the pictures and activating them in nextgen-gallery/view/gallery.php
But after an update of WP, this file isn’t to be found anywhere.
I saw on a forum you should seek now for /wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/ngglegacy/view , but I can’t get any further with this.
The only thing I can achieve is, if you click on the image, this one pops up with a link writen under the image, but when you click on it, you’ll get ‘page not found’. So it stays inside your website.
I’m not a master in scripts, but someone who is, should be able to add something to this plugin, or to the NGG-plugin to make this a whole lot easier

Luckily I made a copy of the htdocs-folder this morning before I started working on the website.
Replacing the htdocs-folder from this evening with the folder from this morning worked for me. Thrown back a couple of hours in work, but the color changing is working again.
I will monitor if it happens again as I make the same changing steps as today.

I’ve got the same over here, at a sudden.
It worked fine, until now. When I go in the customizer to the color changing tab, you see all the tabs which could be selected, except now you can’t selext anything. But you see a small piece of a color setting option, which can be altered, and this used to be the bottem option, for the footer background. This is shown in the left top corner, directly beneath the ‘X’ next to ‘Save’/’Saved’.
I’ve tried a different theme without succes, so it seems to me this has got something to do with WordPress.
Maybe a reinstallation of WordPress will do solve this.
B.t.w. using WP 4.3.1.
