Hi, I'm not sure if I understand what you want but Graphics[With[{h = 0.01}, Table[{Hue[x], Tooltip[Rectangle[{x, 0}, {x + h, 1}], x]}, {x, 0, 1, h}] ], AspectRatio -> 0.125, Frame -> True, FrameTicks -> {Automatic, None} ] May help to make a legend.

There are in this case only 5 colors. Hue[1] corresponds to 5, Hue[4/5] corresponds to 4 etc. > The examples in the documentation do not help me.

Can anyone help here? Maybe there is no need for the explicit Hue in this case and all could be done with just a list of Lines.
