ELI5: If an object is in a shade that we can't see like infrared, what color would it be to the naked eye?

So this question seems like it has a really simple answer, but like how a leaf is green, some objects have got to be in an infrared shade, because there is a giant spectrum of color that we can't see, so if we were to look at the object without any visual help, what would the object look like color-wise?

An objects color is the sum of the colors of light it reflects as opposed to the light it absorbs. So a leaf is colored green because of chlorophyll which absorbs red and blue light well.  This leaves green light to get reflected back.    

If there were an object that absorbed all frequencies of light except those in the infrared which it reflected.  That object would appear black, because no light we can see gets reflected.
