Hue, saturation, and brightness

I was wondering if there is a reason that having a hue of 0, saturation of 1, and brightness of 1 does not produce white. In other applications of HSB, (0,1,1) is white; in fact, (*,*,1) is white. However, in Context Free having (0,1,1) just makes a fully saturated color, and to get white the saturation must go down to 0. Have I made some mistake, or is this how it is intended to work?

You are thinking of the
HSL color space. Context Free/CFDG uses the
HSB (or HSV) color space. Some graphics applications use HSB and some use HSL.

HSB works because the hue defines a color, based on a 360º color wheel. the brighness explains how dark or light it is. The saturation is how much the color is added to the gray. So to have white, you must be completely bright, and completely devoid of color. meaning *,0,0.

Thanks, I didn't realize there was a difference between the two color spaces.
