Although this sequence works reasonably well. Why do the LEDs when they have faded to OFF remain slightly lit when realy they should be OFF?

Also, during the sequence, one LED jumps quickly to another, I have it when BLUE goes OFF, it jumps to RED quickly, then goes OFF again. Are others getting the same, it is quite quick.

Is there any other RGB sequences out there that perform a similar task??

Cheers,

Steve
