They don't appear to be complementary either. The complement to #ee4035 is in the cyan range (~5cf7fa). You can get this by hand.

Convert #ee4035 to rgb(234, 64, 53). Subtract those values from max RGB domain (255) and take square root of difference of squares. i.e sqrt(255^2 - 238^2) etc.

You end up with rgb(92, 247, 250), or the cyan color mentioned above. You can also check this in several other complementary calculators.

I could be missing something.
