Hi everyone,
I would like to dynamically change the textcolor via expressions as I do for the text that is presented - but this does not work.
Does anybody know whether there is a bug in my script or if there is any other way to dynamically change the textcolor of an element depending on conditions?
Thank you for your help!

<text newTaskReminder>
/ items = ("<%expressions.new_task_reminder%>")
/ position = (50%, 80%)
/ txcolor = <%expressions.newTaskReminderColor%>
/ size = (80%, 6%)
/ fontstyle = ("Arial", 3%, false, false, false, false, 5, 1)
</text>

<expressions>
/new_task_reminder={
if(values.targetTask == values.taskA) {
"BUCHSTABE ~n '<%text.letter.#ff2e50%>' ~n'<%parameters.leftKeyLabel%>': <%expressions.letter_left%>              '<%parameters.rightKeyLabel%>': <%expressions.letter_right%>";
} else if (values.targetTask == values.taskB) {
"ZAHL ~n '<%text.number.#ff2e50%>' ~n'<%parameters.leftKeyLabel%>': <%expressions.number_left%>              '<%parameters.rightKeyLabel%>': <%expressions.number_right%>";
} else {
"?????????";
}
}

/newTaskReminderColor={
if(values.targetTask == values.taskA) {
darkmagenta;
} else if (values.targetTask == values.taskB) {
limegreen;
} else {
orangered;
}
}

</expressions>
