# changing background color of a letter template

I found the tuletter class in Overleaf (which loads the article class) and I've been using it for typing letters of correspondence. Now, I want to change the background color of the letter from the default white to another color, say yellow.

To do this, I use \pagecolor{yellow} from the xcolor package. However, the header text/elements can't be seen if this is done (see image below).

I've also used the following code from an answer but the same thing happens as when \pagecolor{yellow} is used.:

\usepackage{ocg-p,tikz,eso-pic} \AddToShipoutPictureBG {\begin{ocg}[printocg=never]{backgroundcolor}{oc1}{1} \tikz[overlay,remember picture]\fill[red](current page.north east)rectangle (current page.south west); \end{ocg}}

My question is how does one change the background color of a letter (preferably tuletter class) such that the header elements can be seen?

EDIT: Here is the MWE of the main texfile tuletter_en.tex (coming from the Overleaf template) and which I edit on Overleaf:

\documentclass[en]{tuletter}
% this package is only needed for demo (\lipsum)
\usepackage{lipsum}
\usepackage{times} %Times New Roman Font

\usepackage{xcolor}

% Signature at the end of the letter are used with \closing
\signname{J. Doe}
\signimage{signature_jdoe} % pjansen is the filename of the image of the signature (i.e. 'pjansen.png')
% if needed a second signature can be given with \signnamesec and \signimagesec

\begin{document}
\pagecolor{yellow}
% show two paragraphs of text
\lipsum[1-2]
\closing{With kind regards,}
\end{document}


Here is the output of the MWE:

I've tried looking at tuletter.cls but my limited TeX/LaTeX knowledge can't seem to grok it.

• You have to provide a complete MWE. I changed page colour to yellow for one of my documents, and headers and footers showed up just fine. – Sveinung Oct 1 '19 at 8:24
• This worked: \documentclass{scrlttr2} \usepackage{xcolor} \pagecolor{lightgray} – Erwann Oct 3 '19 at 6:12

\RequirePackage[absolute,overlay]{textpos}
