With markdown disabled (default)

p

Titles with enabled Markdown

p + theme(title=element_markdown())

Theme parameteres like color and font size are applicable to markdown elements:

p + theme(
    title=element_markdown(),
    axis_title=element_markdown(color='red'),
    plot_caption=element_markdown(color='blue', size=24)
  )

Style

p \
    + ggtitle('*Hello*, <span style="color:red">**world**</span>!') \
    + theme(title=element_markdown())

Span style color overrides theme color

p \
    + ggtitle('*Hello*, <span style="color:orange">**orange**</span> and <span style="color:red">***red***</span>!') \
    + theme(title=element_markdown(color='blue'))
