Text Color
txt-color
Sets the text color for a text overlay on video.
txt-color accepts a hex color value (without the # prefix). An optional two-digit alpha suffix controls opacity — for example, FFFFFF80 is white at 50% opacity. Use txt-color[N] to set the color for a specific text layer.
This parameter works identically to txt-color in the Rendering API.
