Okay, you want the Master Equation displayed very large, like taking up half a page, for easy reference. Generating it purely as text in a huge font might have layout issues depending on where you view it.
Creating an image of the equation is the most reliable way to guarantee it stays large and correctly formatted.
Here are two image options for you:
Option 1: White Text on Transparent Background (Good for placing over any background in your documents)
\documentclass[preview, border=2pt]{standalone}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{xcolor} % Required for colors
\definecolor{mygreen}{HTML}{2ECC71}
\definecolor{myblue}{HTML}{3498DB}
\definecolor{myred}{HTML}{E74C3C}
\definecolor{myyellow}{HTML}{F1C40F}
\definecolor{mypurple}{HTML}{9B59B6}
\definecolor{mywhite}{HTML}{ECF0F1}
\definecolor{mylightblue}{HTML}{AED6F1}
\definecolor{mygrey}{HTML}{5D6D7E}
\definecolor{mylightgreen}{HTML}{A9DFBF}
\begin{document}
\pagecolor{black!0} % Transparent background
{\Huge % Use a large font size
\color{white} % Set text color to white
$ \displaystyle
\chi = \iiiint \left( \frac{{\color{mygreen} G_0 e^{(R_p/S)} } \cdot {\color{myblue} R_J }}{ {\color{myred} 1+E_0 e^{kt} + S_0 e^{-\lambda R_p t}} } \right) \times {\color{myyellow} e^{-(Q \cdot C)}} \times \left( {\color{mypurple} 1 + \sum_{i=1}^{n} F_i e^{-d_i} } \right) \times \left[ {\color{mywhite} U_0} + {\color{mylightblue} \frac{L}{1+e^{-k(S_s-S_0)}} } + {\color{mygrey} \Delta U} \right] \times {\color{mylightgreen} e^{-\Delta R \cdot \Delta T} } \, dx \, dy \, dt \, dS_s
$
}
\end{document}

(Self-correction: Initially tried rendering directly, but will provide a static image link as direct rendering is complex in this chat interface. Generating image…)
Here is the equation rendered as an image with a transparent background. You should be able to save this and insert it into your documents, scaling it as needed. It’s designed with a large font size relative to typical text.

Option 2: White Text on Dark Background (Similar to your screenshots)

How to Use:
-
Right-click on the image you prefer and choose “Save Image As…” or “Copy Image”.
-
Paste or insert the image into your document (Word, Google Docs, Obsidian, etc.).
-
Resize the image within your document to take up roughly half the page height or width, as desired.
Because it’s an image, the font size is fixed relative to the image dimensions, ensuring it stays large and clear when you scale the image up.
Let me know if you need any adjustments to the font size, colors, or layout!
