function colorset {
	style=""
	case $1 in
		text)   style="0;3"  ;; ## regular text
		HItext) style="0;9"  ;; ## high intensity regular text
		bold)   style="1;3"  ;; ## bold text
		HIbold) style="1;9"  ;; ## high intensity bold
		undl)   style="4;3"  ;; ## underline
		back)   style="4"    ;; ## background color
		HIback) style="0;10" ;; ## high intensity background color
	esac
	
	color=""
	case $2 in
		black)  color="0" ;;
		red)    color="1" ;;
		green)  color="2" ;;
		yellow) color="3" ;;
		blue)   color="4" ;;
		purple) color="5" ;;
		cyan)   color="6" ;;
		white)  color="7" ;;
	esac
	
	if [ -n "$style" -a -n "$color" ]
	then
		echo -en "\e[${style}${color}m"
	else
		echo -en "\e[0m"
	fi
}

Use case:

source colorset.sh

colorset bold green
echo "Wow, I'm bold and green!"
colorset 
echo "I'm just plain and normal."

If an invalid keyword for either $style or $color is provided, the style will be reset to the default.

Tip: echo -n TEXT will suppress the newline character at the end of the statement, so you can use different formats on one line.
