Often, but not always, when the colors are the same the wire with the stripe will be positive. It looks like one of your wires has a stripe, but that may just be glare.
If it's an incandescent lamp, polarity doesn't matter (but it will help whoever has to troubleshoot it in 10 years if you get the colors right). If LED, it just won't light and shouldn't do any damage if you get the wires backwards.
