Chromium is Greek 'chroma' — colour — named by Vauquelin for the wild hues in his crucible, yet its greatest trick is transparency: the invisible passivating film that makes stainless steel stainless at ten and a half percent by mass. The element of colour saves the blade by disappearing. That inversion is the reading here.
