For example, if you have a layer of bright blue (0000ff) and you adjust the hue a half circle, you get bright yellow (ffff00) which is way more bright than the blue. Both colours have the same saturation and value in the HSV system, but the other is many times brighter actually...
I believe just impossible have a color seen by human eyes as a "dark yellow", meaning dark as blue...because yellow will be never felt as dark , or if percived as dark would be no more felt as yellow.(but will be see as brown )
you may give more or less brightness to blue,or red, but for yellow you may only add some brightness (resulting in a whiter yellow) but as soon you start to lower its brightness the human eyes refuse to see the resulting color as something close to yellow
Anyway maybe you may found something useful in the "color" submenu of GMIC, as the varius color mixer
