# Change “FIGURE 1:” color, but not caption color

I would like to change the color of the "FIGURE 1:" portion of my caption to blue (including the number & colon), but I want the remainder of the caption to be black. I have tried the following in my preamble, however, the whole caption is blue:

\documentclass{article}
\usepackage{color}
\renewcommand{\figurename}{\color{blue}{FIGURE}}
\usepackage{graphicx}

\begin{document}

\begin{figure}
\includegraphics[width=\linewidth]{../ubmFigures/exampledoc}
\caption{An example figure}
\end{figure}
\end{document}


The caption package provides better control over caption elements. Specifically, you can set the labelfont and textfont to include colour or not. With the elements grouped, just setting labelfont{color=blue} prints the \figurename, number and separator in blue:

\documentclass{article}
\usepackage{graphicx,xcolor}% http://ctan.org/pkg/{grahpicx,xcolor}
\usepackage{caption}
\renewcommand{\figurename}{FIGURE}
\captionsetup[figure]{labelfont={color=blue}}
\begin{document}
\begin{figure}
\includegraphics{example-image-a}
\caption{An example figure}
\end{figure}
\end{document}


A discussion on the options are available from the caption documentation (section 2.3 Fonts, p 9-10).
