Do you have blue or pink coolant?

I'm praying it's a hose. I had a coolant level warning one time. I didn't even add any more and never had another warning, but my mechanic found the buildup in that photo above and wanted to do a pressure test, so that's what's happening right now. He described it as "it'll break, and then we'll order the parts to fix it". Kinda wish he hadn't told me. 😂
