Azazie - Colour Variations

I'm wondering if anyone has had any issues with Azazie's colours being different from each other despite saying it's the same colour. I realize dye lots can vary and that they can't guarantee exact matches, but what I mean is that when you search for all of their mocha coco-coloured dresses, the majority of them look to be the same colour on the website, but then there's a few that look waaaay lighter on the website despite them saying the colour is also mocha coco. It just makes me nervous and am looking for reassurance.
