Custom titlepage in LaTeX - latex

Question

I am trying to create a custom title page in LaTeX according to my organization's template (in Word).
I managed to get close to it with the following code:
\documentclass{report}
\usepackage[a4paper,twoside,bindingoffset=0cm,nomarginpar,includeheadfoot,headheight=1.25cm,headsep=0cm,top=1cm,bottom=1.8cm,inner=1.75cm,outer=1.75cm,showframe]{geometry}
\usepackage{xcolor}
\usepackage{colortbl}
\usepackage{calc}
\usepackage{graphicx}
\usepackage{tabularx}
\definecolor{greenBE}{RGB}{141,182,60}
\definecolor{blueBE}{RGB}{0,111,144}
\title{La qualité de l'air en Région de Bruxelles-Capitale}
\newcommand{\subtitle}{Rapport annuel 2019}
\author{}
\usepackage{lipsum}
\begin{document}
\makeatletter
\begin{titlepage}
\thispagestyle{empty}
\newlength{\rulewidth}\setlength{\rulewidth}{3cm}%
\newlength{\logowidth}\setlength{\logowidth}{2.5cm}%
\newlength{\logoheight}\setlength{\logoheight}{\logowidth*\ratio{592pt}{1538pt}}% image size : 1538 x 592
\begingroup
\setlength{\tabcolsep}{0pt}
\renewcommand{\arraystretch}{0}
\noindent%
\begin{tabularx}{\textwidth}{p{\rulewidth}c>{\centering}X}
\cellcolor{blueBE}&\includegraphics[width=\logowidth]{ILLU_FR_LogoBE.jpg}&\cellcolor{greenBE}\color{white}{RAPPORT TECHNIQUE}
\end{tabularx}
\endgroup
\vspace*{3cm}
\color{blueBE}
\raggedleft\MakeUppercase{\Large\textbf{\#title}}\\
~\\
\raggedleft\large\textbf{\subtitle}
\vfill
\raggedleft\MakeUppercase{\Large\#date}\\
\vspace*{4cm}
\noindent%
\color{blueBE}{\rule{\textwidth}{\logoheight}}
\end{titlepage}
\makeatother
\restoregeometry
\tableofcontents
\chapter{Prerequisites}\label{prerequisites}
\lipsum
\end{document}
and the image logo ILLU_FR_LogoBE.jpg
However, as you can notice below, the text "RAPPORT TECHNIQUE" on top of the first page is enlarging the height of the row. Instead, I would like to center it vertically in the middle of the logo.
What am I doing wrong ?
Many thanks,
Alessandro

You could use \usepackage[export]{adjustbox} and then play around with different valign options for the graphic.
\documentclass{report}
\usepackage[a4paper,twoside,bindingoffset=0cm,nomarginpar,includeheadfoot,headheight=1.25cm,headsep=0cm,top=1cm,bottom=1.8cm,inner=1.75cm,outer=1.75cm,showframe]{geometry}
\usepackage{xcolor}
\usepackage{colortbl}
\usepackage{calc}
\usepackage{graphicx}
\usepackage{tabularx}
\definecolor{greenBE}{RGB}{141,182,60}
\definecolor{blueBE}{RGB}{0,111,144}
