How can one change title, color, and font size in the beamer package ?
My MWE is:
\documentclass[10pt]{beamer}
\usepackage[utf8]{inputenc}
\usepackage{charter}
\usepackage{tikz}
\usepackage{graphicx}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{multicol}
\usepackage{wallpaper}
\usepackage{IEEEtrantools}
%\setbeamerfont{subsection in toc}{size=\tiny}
\setlength{\footnotesep}{0pt}
\newcounter{saveenumi}
\newcommand{\seti}{\setcounter{saveenumi}{\value{enumi}}}
\newcommand{\conti}{\setcounter{enumi}{\value{saveenumi}}}
\resetcounteronoverlays{saveenumi}
%% Title slide formatting %%
\pgfdeclareimage[width=\paperwidth]{titlebackground}{put here any image}
\setbeamerfont{subtitle}{size=\tiny}
\setbeamertemplate{title page}{

Best Answer
To change the title font size, you can use the exact same mechanism as you already do for the subtitle:
\setbeamerfont{title}{size=\Huge}
The colour is a bit trickier as you define your title page yourself. If you add
\usebeamercolor[fg]{title}
to your custom title page, then you can change the colour via\setbeamercolor{title}{fg=blue}
Of-topic: you don't need
graphicx
with beamer and instead ofmulticol
andwallpaper
beamer has its own mechanism for columns and backgrounds.
