Re: What is HB(V) color space?
There are two adaptations/variations of the RGB space, one called HSB (hue/saturation/brightness) and one called HSV (hue/saturation/value). They are essentially the same. It could simply be a case where someone passed along a scribbled note and asked their assistant to post it, in which case it got messed up; or the person simply forgot the correct acronym and went for it. Some of us know what it's like when we start getting old(er).
Each of these is also a slight variant of HLS (hue/lightness/sat) which is much more common. In HLS, white is defined as when L is highest. In HSB, when brightness is maxed out, color is at its brightest (not white).
