Help - out of gamut colours / borked palette?

So what Gimp it telling you is that you can't just get a darker color (lower L) without altering c and/or h. If you change the dialog to HSV model (which is just a plain mapping of the RGB values), then you can change the V (which is close to the brightness, but not exactly the brightness) to darken the color, but of course you'll have a slight hue change in the Lch model.

OK, so I understand what you're saying here I think - that if I switch to HSV I should be able to darken the hue using V. The problem is that even with HSV selected, I can only lower V to ~75 before it changes to this really vibrant blue instead of the pale one I'm using.

Also, looking closer at the colour selector, once V drops below that value, this new colour also shimmers in the selector, as if it is animated, not a flat hue. I can't show this in an image of course, but this is what it looks like with HSV selected (essentially the same as with LCH).
