Home Assistant makes colored gauge ranges editable without YAML. Gauge cards gain a color-mode selector for a single color, the existing severity thresholds or individual segments with a starting value, color and label. Tile-card bar gauges gain a segment editor too.
Existing segments that use supported color names such as red and green follow Home Assistant’s theme colors instead of the browser’s fixed shades. Owners who need the original exact colors can use hexadecimal color values.
