Just editing this negative review saying it doesn't work.
I managed to miss this for an embarrassingly long period of time: If you still get US spellings after installing this dictionary right click any in text box, click, select "English / United Kingdom".
Then enjoy typing colour properly to your hearts content.

This review is for a previous version of the add-on (1.19.1).
