## Using light grey on the letters inside the box

To ensure the students tick the correct box in a matrix, I've put letters inside them so they're easy to identify. This makes the detecting threshold more critical. Is it possible to choose the colour of the letters that are put inside?

I would like them to be in e.g. 40% grey.

From revision r1267, this can be done with something like

\def\AMCchoiceLabelFormat#1{\textcolor{black!40}{#1}}

Other solution: ask the students to fill the boxes completely, and use a "drakness threshold" around 0.6

I've tried this in the latest version, but I'm not the kind of guy who compiles an intermediate release.

Nevertheless, I found a Latex command using colour that did the trick:

\usepackage{color}...\def\AMCchoiceLabel#1{\color{black!40}\alph{#1}}

which work like a charm! Nice weak, minuscle letters inside the boxes used in questions.

My next issue is that I would like to format the \AMCcode (box matrix used for studentID) to also show a weak digit inside the box.

\def\AMCcodeLabel#1{\color{black!40}\alph{#1}}

did not work. Any ideas?

Ths first command I wrote works for both choices boxes and codes boxes. On Ubuntu, you can use development version of AMC from the test PPA repository.
