I had no income tax withheld and owe no income tax to the state of Colorado. Am I required to file a Colorado state income tax form?

[JN1]

Is it "No, return is needed to be filed (unless you are filing to get a refund)" or "No return is needed to be filed for CO if I am a NR and have no other income from that state"

No, return is needed to be filed (unless you are filing to get a refund). 

Who Must File This Tax Return Each year you must evaluate if you should file a Colorado income tax return. Generally, you must file this return if you were: • A full-year resident of Colorado, or • A part-year Colorado resident who received taxable income while residing here, or • Not a resident of Colorado, but received income from sources within Colorado, and • Are required to file a federal income tax return with the IRS for this year, and • Will have a Colorado income tax liability for this year.
