It’s weird. This does not behave as I would expect, which would be a consistent change in hue across the cube, but rather it produces an almost flashing effect. Is hue not linear?
Easier to show than explain, so load up the attached and press play to see what I mean.

Not seeing any ‘flashing’ in 2.83… Which version of Blender are you using?
The same with 2.83 and 2.90. Flashing is probably the wrong word, but the hue shift in the different bands is not consistent, as in each band seems to shift at a different rate, rather than the smooth transition across the whole object that I would expect. More of a pulse than a flash, but not a consistent pulse across the object.
I think what you’re seeing is that as you animate linearly through the hue in hsv space, the perceived brightness does not correlate to the hue, also the blue space is much much larger than say the yellow.
That does kind off make some sense. I guess I need to study hue more, since it is clearly not a linear transition.
Not that it’s important to me right now. I was just playing and it confused me.
Thank you.
The other thing is that you have created those color stops, and you are then offsetting those hues. We perceive colors much much differently when they are next to different colors. So as those color pairs animate the difference in hue and innate brightness is all over the map, and definitely not smooth. You’d get a better idea of the hue animation if instead of plugging in your color ramp into the HSV mode, unplug it and make it pure red.
I get that. I was actually experimenting with the relative value of colours rather than hue to start off with, and the HSV node was a quick and easy way to desaturate (and yes, it just becomes a solid white-ish colour then). The hue was entirely experimental, but the result surprised me.
