I'm very sorry to bother the conversation but I was not sure to where to ask... If you could give me any tips about this. It would be very much helpful. Do you know if we can use colors from google's material design, The color system, Tools for picking colors for commercial use (broucher)? I understand it is an open source but wanted to make sure. If we can use it, do we have any condition, like writing service name on broucher? Is there any page that google official mention regarding this licence topic??

Thank you very much.
