Hi @sofiaminetto, that color of blue appears several times in the theme’s CSS: as background colors, buttons in different places, other types of buttons, etc. Are you hoping to replace all of them for the green color, or just in the cases you’ve mentioned?
I’m going to go ahead and give you CSS for all of it, then you can remove any parts of it you don’t want to be green:
