Gauge needle type of Advanced with some combinations of NeedleColor1 and NeedleColor2 (mainly lighter colours?) there is a noticeable border around the needle 'hub' of a different colour.
More noticeable with larger NeedleWidth.
Attached jpg shows effect with newly placed gauge with only changes being:
- NeedleWidth 6 (to highlight problem more clearly)
- NeedleColor1 Magenta (why the very limited choice of colours?)
- NeedleColor2 Cyan
Hub border is actually more prominent on screen - jpg has blended the colours a little and muted it. (bmp attachment wasn't permitted)
