On macOS High Sierra (version 10.13), this is now quite simple. In Mail.app:
First open the toolbar if it is not already on. This can be enabled by clicking the toolbar with the letter "A" in the upper right corner of the creation window. By doing this, you can:

- Select a highlight color.
Thatβs all there really is.
