In Preferences, Colors, Custom, it seems that you can change the Saturation and Brightness of a given setting within the scheme, but NOT the Hue.
You -can- change the Hue for the overall preset, but that changes EVERY option for the colour scheme.
So it seems like yer limited to setting a Hue (eg. ‘Red’) and then each sub-setting has to be within that Hue.
That’s not good for me.
Is this a bug or am I missing something?
