chromeForeground property
Color
get
chromeForeground
Icons and secondary text drawn straight on the background (the toolbar): previewText, or — when a displayFace puts the display text on its own panel, so previewText is solved against the panel only — the focusRing colour, which is ≥ 3:1 on every background sample.
Implementation
Color get chromeForeground => displayFace == null ? previewText : focusRing;
