Why did my nickel + hydrogen peroxide turn red?

So I recently thought of doing some electroplating and bought some nickel strips from Amazon. As I was making the acetate solution I added some hydrogen peroxide (6%) because I wanted to see if nickel would form nickel acetate the same way copper acetate is made by reacting copper with acetic acid (I had disconnected power). To my absolute surprise the color of the solution changed from crystal clear to almost blood-like red.


Could someone tell me what products I may have made?


Could it be that my nickel was not pure and contained some impurities? The seller claims it's 96% pure and its the sort you'd use for spot welding but I'm not sure.
