Sign Customiser’s Flow RGB effect has been completely redesigned. Instead of filling the entire shape with animated colours, the effect now animates along the outline of your text and logo designs. This creates a more realistic neon tube simulation and unlocks the ability to use Flow RGB alongside a face colour for the first time.

## What’s Changed

- **Animated outline effect**The Flow RGB colours now cycle smoothly along the stroke/outline of text and SVG shapes, creating a realistic flowing neon tube appearance
- **Works with UV colours**You can now combine Flow RGB with a solid UV colour, where the animated gradient appears as an outline around the filled shape
- **AI sign design support**AI sign designs now display the same animated outline effect with thicker, more visible strokes optimised for complex shapes
