New color wheel with Hyperion

I like the new colorwheel. However with Hyperion I now have no possibility to dim the lights, as the Hyperion component does not show a dimmer. With the old Square color select it was possible to dim.
Is there any chance to technically implement a dimmer function for hyperion lights as well?

sorry to dig up this old thread.

I use Hyperion as driver for my lamps in HA and it works just fine.

but with the current color wheel there is no way to adjust brightness for the lamps bc hyperion needs absolute RGB values. So while i can change colors, the lamps will always be at 100% brightness (the brightness slider does nothing).

Is there any way to manually re-implement the old color picker with the black and white values (c.f. screenshot below)?
