Hi, did you mean one color besides black? or it has to be only one color for all, referring to the logo attached black and orange for example, can we use this combination? or it must be black only or orange or any other color on a white background??

Thanks for question, logo won’t go on it. One colour for all which will be white. I included the style guide so you can see the fonts I use some times Thanks.

thank you for inviting me. what is the size for each design
