Colour Cycle that actually works

So, I’ve tried the colour cycle through many different updates and it still doesn’t really seem to do much more than change between 1-2 colours regardless of what degree I put the bottom setting on, I only have one bulb, surely there’s an effect that could easily be released that would go through the whole thing in a 360o shift?

Call it “Rainbow Whirl” or something and let it go all the way around the spectrum at set variable speeds or brightness shifts etc.
