Our templates are carefully designed to provide appropriate contrast and readability. It is always best to avoid custom colors, especially red and blue. The colors are both too strong and fight to overpower each other, which plays tricks with our eyes or make the page hard to read on screens with varying brightness levels.
If you need to draw attention to text on a page, bold is always the best option. If you feel that bold does not get the result you are looking for, you can contact the webteam for other possible options.
