Add software color temperature (Kelvin to RGB) slider to the menu

[waydabber]

Feature Request

Add additional software (gamma table) image control slider for color temperature. The presence of the control should be optional (user selectable) and only for displays with gamma table control.

For future reference: use the following to convert Kelvin (color temperature) to RGB:

(note: it is debatable whether color temperature control should be a scope of MonitorControl or not).

Impressive demo in your link:

Should this be a function in MonitorControl? I don’t know. Do it want it on my Mac? YES!

I’ve played about with custom colour profiles a bit over the years but this is so much better. One slider to rule them all.

+1 to the addition of this feature. I agree that it's debatable whether this should be a function within MonitorControl.

Having MC be able to do this function vs. competing with another program (such as Iris) on the device would be great, and very streamlined. Additionally, adjusting brightness and color temperature are two tasks I often do together.

If anyone has found a workaround apps that pair well with MC would love to see them. So far Gamma Control app, and Iris both work ok, but trigger a warning within MonitorControl.

Is your feature request related to a problem? Please describe

I'm looking for a % of currently set brightness. Also, I want to change Color Temperature.

Describe the solution you'd like

I forked and improved NativeDisplayBrightness app. Initially it was without any UI. I added:

• status bar with % of brightness
• ability to change system option of Temperature.

Can you please add such options in this amazing app? Thanks!
