Opinons on princess diamond please

[star18]

I am hoping you can all help me out. I am trying to choose a princess diamond. I am still a little unsure about what the blue means on ASET image. I know black/white usually means leakage. But what about blue? Here are the links. I would LOVE your help. So much appreciated. Thank you.

They all face up similar sizes and I'm leaning toward #1. However, I do like the table in the 3rd one. If only #1 had that. Thank you!

Also, opinions on how much larger a 5.25mm (ish) princess will compare to a 4.9-5mm (ish)?

This is one I have in mind, slightly smaller...

You cannot go wrong with a Whiteflash ACA princess cut diamond. Most people can see the size difference if the two stones are side by side, but probably not if viewed individually for a 0.25 mm difference.
