Color Picker display settings

The display area of the color picker is showing yellow to violet or green to blue (depending on the vertical slider) rather then the usual white to black with the color range in the vertical rectangle.

Doe anybody know how to change this setting I haven't found it anywhere.

Thanks, Bill

This is macOS9 and PS7

In the right hand side of the colour picker, next to the letters HSL, RGB and Lab you will see some radio buttons, click on them to change the display on the picker.

Thanks

Bill
