regular expression for validating multiple fixed strings

I currently have a regular expression that allows for the string 'red' in lowercase, uppercase and with spaces surrounding it:

/red/i

How would this regular expression be extended to check for multiple words such as rot, rouge, red and rojo.?

I am using a Javascript plugin which does not support flags. This regex also takes the same form in JavaScript in a none literal format, how would this be extended in the same way?

^\s*[Rr][Ee][Dd]\s*$

There are many dialect's of regular expressions. However, in this case the following would work in most cases:

/red|green|yellow|blue/i

Try using the OR operator in your regex:

/(blue|green|red)/i
