Our signature font is Bree Serif which you can download via Google Fonts.
It is also worth thinking about visually impaired, dyslexic and colour blind people when thinking about font type and colour.
Verdana is supposed to be the easiest font to read.
You should also think about colour contrast – some of your audience may find it difficult to distinguish between red and green, and any shades close to each other in colour may be difficult to read.
Dark colours in size 16 pt or above is easiest for those who are visually impaired.
