I am quite news to graphic design so I don't know how to define it better.
I use to design my presentations and some mockups based on complementary colors. e.g. yallowish and orangish as complementary colors.
However when it comes t particular colors (white, black and closer ones like gray scale, yellow..) I have no clue how to obtain the complementary color (if there is an appropriate one) to make the text visible, while being complementary.
What would you advice in this case?
