Which hair color would look best?

Kat

My hair is long enough to get extensions now.. finally! I know what cut i want, which is pretty much the blonde ombre's cut. Now the colors in both pictures I can't choose.. Its just easier if someone just tells me what would look good cause I'm not sure.

The first picture is just what I look like. This is a old selfie is of me so my hair is much longer now.

I just want to feel pretty again and look good for my fiance..

Should I get the blue ombre or blonde? :)
