Colors not quite how I need them to be in studio

Hello! I’m working on guis for my game, and to save time i made the buttons white and gray so i can simply change the imagecolor property in studio, but I’m having an issue, the colors just arent how i need them to be.

this is what i mean, I need the colors to be the same as the one in the top
image

so i export and inport in studio the white one, and this is the closest ive gotten to the result i want:
image

does anyone know an alternative to this?

hmmmm is it possible to…

color pick from the image

or

use the blue button that you do like?
