[Tex/LaTex] Making colorbox left align

horizontal alignmenttcolorbox

I am using same template for resume as was written about here, Latex – width of the colorbox. I am trying to align the words in the black boxes to the left. They seem to be aligned to right as default. How can I accomplish this?

I believe the crux of it is in the \colorbox, but I tried adding \left, but it does not work. I am not seeing any examples of changing alignment either. I look forward to any help!

EDIT: Below is a MWE incorporating the suggestion by David Carlisle. I am trying to left-align the white text in the black box. Whether I use \raggedleft or \raggedright, when I compile, the word Software appears on the right-aligned side of the box:

%%% ------------------------------------------------------------
\documentclass[paper=a4,fontsize=11pt]{scrartcl}                % KOMA-article class
\usepackage{amsmath,amsfonts,amsthm}                    % Math packages
\usepackage[pdftex]{graphicx}                               % Enable pdflatex
\usepackage[svgnames]{xcolor}                           % Colors by their 'svgnames'
\usepackage{geometry}
\textheight=700px                                   % Saving trees ;-) 
\usepackage{url}                                        % Clickable URL's
\usepackage{wrapfig}                                    % Wrap text along figures

\frenchspacing                                  % Better looking spacings after periods
\pagestyle{empty}                               % No pagenumbers/headers/footers
\usepackage{sectsty}                            % Custom sectioning (see below)

\begin{document}

PUBLICATIONS

\noindent \colorbox{Black}{%
            \parbox{6em}{\raggedleft
            \hfill\color{White} Software}} 

\end{document}

EDIT 2:

I am noticing that this convenient line does align the text in the direction as indicated! However, for some reason, the width of the text box does not seem consistent. Below is a MWE showing this:

Best Answer

to right align text in a \parbox use

  \parbox{6em}{\raggedleft

(The colorbox is not really involved at all)
