I the attached code sets the background colours of the element buttons.
If you know how to set foreground colour, you can add it easily.

You can use my quiz class, which generates a series of questions in random order
about seven of the properties of the elements in the periodic table. The questions can
be about the first n elements, where n is user selectable, and are of the form, given
all the details of the element except one, what is the missing detail?
I hope I can use your code in Table?
