Adding more text to a variable

Is there a more simple way to add text to a variable
I have
Code:
var="blue"

and like to add green
to get
Code:
echo $var
blue green

Here is how I do it.
Code:
var=$(echo "${var} green")

This works fine
Code:
var="${var} green"

$ echo $var
blue green

Note that the braces aren't needed either unless what you want to add to the variable could be interpreted by the shell to be part of the variable name.
Code:
var=blue
echo "$var"
var="$var green"
echo "$var"
var="${var}red"
echo "$var"

produces
Code:
blue
blue green
blue greenred
