Emphasising certain words by using colour codes


I would like to emphasise certain words by putting them in a different colour. However, the colour code immediately applies on the rest of the sentence too.

For example:

% font color #BA1714 % ~To do:~\ alpha.

In this sentence, I only want “to do” in the specified colour and not “alpha”. The colour code will be applied on “alpha” too.

How can I change this?

Thanks in advance!
