If you saved a pattern you've colored-in with Rapid Resizer, to change it's coloring:
- Go to your saved designs here.
- Load the design you want to change the coloring of.
- You'll be taken to the resizing page. There you can click Customize then Color.
If you alter a colored design using other Rapid Resizer tools (crop, arc, Designer, etc.) you won't be able to re-color that. So try to finish the design's shape before coloring. If you need to change a colored design's shape, you can change the uncolored original, then use the Coloring page's Recolor button to copy the coloring from the saved coloring of the previous version.
