On our way to TLJ release there is a book telling the story of who appears to be someone who is not a big fan of Phasma.
From what we have gathered from reliable sources, the armor is red, the gloves at FO gloves in red and the boots will be black with a low heel, the very same phasma seems to be wearing.

The boots are in the work but the glove are now available.
