Hey guys I have a question

I wanna put a check side stripe on my laser blue S, I saw them Aesthetic Creation and mighty stripes and they have different options to pick the color.... my question is I am not sure what do they mean

in Aesthetic Creation they have "check color" and "pinstriping"... I think I know what the check color means but what does pinstriping mean? do they mean they top and the bottom of the stripe so it will match your body color?

in mightstripes they have the base color and the secondary color... that I have absolutely no clue what color they are referring to... is it a black and white check or what?

it would be nice if someone have experience with these 2 companies can share they thought on what color option I should pick to order... I want a black and white check... thats it
