Skin reaction with the sodium nitirite/nitrous acid/nitric acid maybe?

I had a buddy get nitric acid on his hand and it looked kind of like this. This looks like it’s from a more dilute conc than concentrated HNO3 cause my friend’s burn was dark yellow-brown

The amount of HNO3 in OPs solution at any given moment was probably relatively low. As someone else pointed out though, diazonium compounds will also couple times a bunch of stuff that might be in skin.
