I once applied more moisturizer than normal & it made my makeup sort of weird. Not orange, but weird & it did darken/oxidize. Maybe adding more of your moisturizer & primer than usual made it change? Sometimes more sweat in summer might add extra moisture too & make it do weird things. Maybe you can try it again w/ usual amounts of moisturizer & see if it still turns on you? Hopefully no one else noticed it but you.
