Remy Bobbi Boss Indi Ocean Wave hairstyle question. Will partial blond look too fake?

Hi, I'm getting weave put in and from what I've seen on YouTube most people prefer to use the Bobbi Boss Indi Remy hair in a darker color like 1b or 2. No one seems to use a lighter color. I think I want 80 percent in a 4 on the bottom (should I use a 2? I chose 4 because of the type of highlight that I want) and the upper 20 percent to be in the P4/27/30. It will be like a partial foil if it were my natural hair. My natural hair (which is long) is partial foil blond on top and a medium brown underneath. I really like the blond color and I want to mimic that color effect somewhat. How do you think this will look? I did see one lady on YouTube with a lot of blonde but it looked really fake. Will my color combo look "faker" than the darker hair that I have seen on the majority of people?
