+# ComfyUI ColorCode Bridge
+
+Tiny type adapter for workflows where one node outputs a hex color string and another node requires a `COLORCODE` input.
+
+## Node
+
+- `utils/color > String To ColorCode`
+
+## Usage
+
+Connect an automatic hex-color string output such as `#00FF00` into `color_hex`, then connect `color_code` into the downstream `COLORCODE` input.
+
+This node validates and normalizes:
+
+- `00FF00` -> `#00FF00`
+- `#0F0` -> `#00FF00`
+- `#00ff00` -> `#00FF00`
