It appears that the metallic parts of the countess dress suffer from the “Red pixel” but where if you zoom out from your character all the metallic parts will turn red and the “redness” scales with how far the camera is from your character. The screenshot I attached shows the effect, I have the chain dyed black but zoomed out it appears red.
While a minor thing, I noticed this playing my character because being an old GW1 player I remember the Elementalist Asuran armor suffered from the same bug in that game.
