If I’m writing a business plan, I’m more interested in typography than I am in colors. It’s only in the last few years that color has become more important to me. I think the main reason why is that so many designers only use typefaces in their print and web design. I’m not saying I’m not a designer, but I’m talking about the typefaces that are most commonly used in the design world.
Its all about the typefaces that make your content readable and most relevant. Typography is a very important part of communicating with your audience, so if you are not using the right typefaces its going to be harder for the readers to understand what you are trying to say.
So you can use a font that will be easy to read, but not as important to you as the typeface that is going to be more prevalent in your audience. This might be a good time to do a little research and see which typefaces are most common, so that you can use them more often.
I have found that using the same typeface with different styles is a good way to highlight your branding if you are using two different typefaces for different purposes. For example, if you are a musician and want a more professional looking typeface, then choose a font that is bold (and therefore easier to read) and use a style that is bold (and therefore easier to read) for writing.
If you are using a different typeface for different purposes, or if you are using a font that isn’t in the most common typefaces, then you are likely to have confusion and frustration when you need to use the same typeface in different situations.
