7 Segment Display (But the 7 Are odd) 

That’s the 7 used in my watch.

1 to 10: Red 11 to 20: Orange 21 to 30: Green 31 to 40: Cyan 41 to 50: Azure 51 to 60: Blue 61 to 70: Indigo 71 to 80: Purple 81 to 90: Lavender 91 to 100: Pink

21 segments

The number 7 is not odd. The odd 7 looks like a twisted F.
