P: Selection of colours mixed up in Hugh / Saturation

Hugh / saturation:
The selectable colours shifted 1 to the left
yellow = red
green = yellow
….

Example: select the yellow button and the red slider appears. The colour red changes in saturation or lightness, depending on the slider used.
In the released version 27.10, red is the first button (correct) 
In the ßeta 27.11, yellow is the first button, but it changes still red

It's very confusing to use.
