Marble Gray and Baby Blue are pretty similar..

Baby Blue is pretty pale, but definitely blue. However, when I placed it alongside marble gray, it really brought out the gray tones in the baby blue. I wasn't sure what Sarah was going for in her enclosure set up. I decided better safe than sorry, and included extra sky blue links! Those are very bright and definitely a higher concentration of blue. 

Here's what Sarah had to say:

"Seller was so kind and included a couple of extra links because they weren’t sure if the color would be to my liking. Above and beyond, will be ordering again."
