Я пишу документацию по стилю и хочу сделать ее визуально привлекательной, обновив документ с помощью цвета обложки.
Основная идея — автоматически обновлять цвет обложки в зависимости от месяца, когда был составлен документ.
Цвета обложки определяются как coverBackgroundи coverFont.
\documentclass[12pt,a4paper]{book}
\usepackage[margin=2cm]{geometry}
\usepackage{xcolor}
\definecolor{grayOne}{rgb}{0.95, 0.95, 0.96}
\definecolor{coverBackground}{rgb}{0.952, 0.929, 0.858}
\definecolor{coverFont}{rgb}{0.223, 0.239, 0.313}
\usepackage[backgroundcolor=grayOne,linecolor=white]{mdframed}
\begin{document}
\begin{titlepage}
\begin{mdframed}[backgroundcolor=coverBackground]
\centering
\vspace*{.25\textheight}
\textcolor{coverFont}{\Huge Page title}\\
\vspace{10pt}\par
\textcolor{coverFont}{\today}\\
\vspace*{.25\textheight}
\end{mdframed}
\end{titlepage}
\end{document}
У меня также есть файл утилиты, в котором я определил большой набор цветов, было бы здорово их использовать.

Вы можете использовать команду \ifcase\monthдля определения различных цветов, например:

Я показал оба метода, определяя цвет напрямую с помощью \definecolor{coverFont}или используя другие ваши предопределенные цвета с помощью \colorlet{coverFont}. Я использовал стандартные цвета, чтобы показать основной способ, пожалуйста, измените его на нужные вам цвета. Последний \else— только для того, чтобы иметь регулярный выход, если месяц не распознан (не должно происходить, но конечно, конечно ...).
При заданном MWE получаем результат:
Ладно, извините, я знаю, что цвет ранит... Но для примера...
решение2
Для реализации механизма разветвления вы можете заставить LaTeX вычислить целочисленный параметр \month.
Механизм разветвления может быть основан на \ifcase:
\documentclass{article}
\begin{document}
The date of compilation is: \today
\ifcase\month This should never be done.% <- case month = 0
\or This is done in January.% <- case month = 1
\or This is done in February.% <- case month = 2
\or This is done in March.% <- case month = 3
\or This is done in April.% <- case month = 4
\or This is done in May.% <- case month = 5
\or This is done in June.% <- case month = 6
\or This is done in July.% <- case month = 7
\or This is done in August.% <- case month = 8
\or This is done in September.% <- case month = 9
\or This is done in October.% <- case month = 10
\or This is done in November.% <- case month = 11
\or This is done in December.% <- case month = 12
