How to change button's background between two colour？

Is this a feature relevant to companion itself, and not a specific module?

• I believe this to be a feature for companion, and is not specific to a module

Is there an existing issue for this?

• I have searched for similiar existing issues

Describe the feature

For example：press→black，press again→red，press again→black，change between two colour?

There's several ways you can do this, for example if you're using Steps then you can use the Expression function $(this:step) === 1 ? 0 : 0xff0000 for the background fill colour of a button, which if the step is 1 then it'll be a black background, otherwise it'd be red.

Alternatively you could use a local variable, for example make a local variable called bg, set it to use JSON mode rather than text and a value of true, then put the internal: Local Variable: Set value action on then button that's targeting bg, and the value is !$(local:bg) which will just flip the value between true/false, then the background fill can be set to $(local:bg) ? 0 : 0xff0000.
