Change black text to white

Hi I am sure this will be completely obvious and I have overlooked something, but I am unable to see where I can change the colour of the text, particularly from black to white?

Refer to figure 15.6, on page 390 of the user manual PDF, for a screenshot of the Format Bar. The buttons marked (d) are for setting text and highlight colours, in that order. As described on the following page, right-click on the tool to set the colour, left-click to use it.

Note there is also “Remove Color” option, the one with a red slash through it.
