microbit.org-ticket: 456

Customer has reported that having a default value of 100 for L, means that the RGB equivalent is always white (as opposed to HSV which does not suffer this side effect). The UX of this is therefore slightly strange, because changing H or S does nothing with the default value for L=100.

Could I suggest perhaps setting default L=50 so that then any change to any of the 3 parameters will make a visible change to the output?

Default for HSL (L=100) always generates white

Also the colour swatches for HSL on this page, make it obvious that this is indeed the case for L=max:
