Remove the stroke or fill color of an object
- On the Inspector, click the Stroke or Fill tab.
- Click None from the drop-down list.
If you specify a stroke or fill value of None, the value cannot be animated. To animate a stroke or fill color, you must select both a starting and an ending color; You cannot animate the starting or ending values from None to Color.
To transform to or from a transparent stroke or fill value, use the Alpha slide bar of the Color panel to define the opacity of the stroke or fill; an Alpha value of 0 will render the stroke or fill completely transparent. You can animate the value of the Alpha channel. If you want to animate both the stroke and fill values together, you should animate object visibility or object opacity rather than animating the value of the Alpha channel for each property independently.
