Narrative:

Windshear was reported; cleared for the visual approach; stable at 1000 feet; windshear warning at about 500feet. I expressed concern for the go around; captain said 'no no; that's a caution message;' landed. I asked captain to explain his actions. Flying into ZZZ we were told there was windshear and windshear conditions reported. The captain was pilot flying and I was pilot monitoring. Upon being told about the conditions I put the continuous ignition on and briefed the captain that if we get a windshear warning that we would go around and fly to the published missed approach point. Once clear for the visual the aircraft was stable at 1000 feet where I made the 1000 foot stable call out. Around 500 feet the windshear aural alarm went off with the warnings displayed on the pfd. I said 'are you not going to go around;' the captain said 'no that's a caution' and continued to then land. Once on the ground walking through the airport I pulled the captain aside and asked him to explain why he chose to continue to land when I thought that the indications that the plane was giving us was a warning in which we needed to execute a go around procedure. He explained his reasoning as to why he thought it was a caution that was being displayed. I expressed why I thought it was incorrect and the conversation ended. Getting back to hotel room I researched what I found to be that I was correct in the sense that the alarms and messages were for a windshear warning and we should have gone around. I could have been more assertive to make the captain go around.
