With color support enabled, the option to add color for the button element is enabled on the parent buttons block, is that correct?

Thanks for testing @carolinan 👍

This PR only proposes to add background color support to the wrapping Buttons block rather than text color for all internal buttons. With the way individual buttons are structured, I'd like to address text color for inner Button blocks separately.

[carolinan]

I meant this button color support: "color (background, button, gradients, text),"
With this option, you can set both the background and text color of the inner button.

Sorry @carolinan, I'm not following 😅

Is the confusion that the docs strike out the text support to show it has been opted out of?

You'll see that the text color support for the parent Buttons block is disabled here.

[carolinan]

No, I am finding it confusing that the parent now has any settings for the inner button.
(One of the reasons why it is confusing is the problem where the controls on the inner button do not show the inherited colors)

I only mentioned the text because I interpreted this as it should not be possible to set the text color on the inner button from the parent:

Thanks for the clarification, I think I'm on the same page now 👍

What's highlighted in the screenshot is actually the button element styles not inner button block controls. I'll see what I can do to reduce the potential for confusion here.

Yes 😄

[aaronrobertshaw]

Apologies for my earlier confusion @carolinan.

It was staring me in my face and I kept reading the config as background not button 🙈

Now my tunnel vision has dissipated, let's leave the element styling out for now. While it does give users the option to bulk style all buttons it can be confusing. Discussing or implementing that as a separate follow-up sounds like the best path forward for now.
