Hello,
Thanks for your question regarding the color customizations you are making not appearing on all your pages. I’m sorry to see that there is an issue that you are experiencing. The color customization should apply automatically to all the Active Pages (as long as they are not Staging).
If applying the changes to the Active theme in the Customizer tool, then please let us know more details, like the Inspiration you are using and the version of any BoldGrid plugins you have installed. If you are using any other builder type plugin, be sure to disable it and check if the issue is resolved.
I hope this helps.
Sincerely,
Carlos D.
