q-toggle color for false state (and no color for indeterminate state)

[FragsterAt]

Is your feature request related to a problem? Please describe.
I want to use q-toggle not like on-off (checkbox), but like select between two equal values
Now it seems like this:

But I want to see it like this:

Describe the solution you'd like
Option false-color to add color and bg for 'off' state

Describe alternatives you've considered
Alternative is button-toggle, but it is not clear for users, when it is only two values

Hi @FragsterAt, we follow material design guidelines and the behaviour you ask isn't what toggles are made for.
You should probably use QRadio/QOptionGroup component for a selection between 2 "truthy" values.

I checked around and seems like all other frameworks agree on this, so we probably won't accept your PR.

Will leave open in case @rstoenescu wants to weight in confirming/contradicting what I wrote.

As rejecting a PR isn't nice either for Quasar team and the PR maker, please follow the PR guidelines next time and wait the green light before sending a PR.
We love to have an actively involved community which help us with bugfixing and new features, but we want to avoid wasting community members time on PRs which aren't sure to be accepted :)

@IlCallo , I looked at https://material.io/develop/web/components/input-controls/switches and find options toggled-off-color($color) and others to set custom "off" color, even different colors for track, thumb in every state.

True that, do you have examples from other UI libraries?

@IlCallo
there is links to custom components, where i can change false color without making changes in lib, only by my own styles (time limit for finding way to set false-color was one minute):
