This would be for both GenerateBlocks Pro and GeneratePress (maybe it’s a GP Premium feature that detects if you are using GenerateBlocks Pro)?
Basically a global color palette that would allow users to easily update master colors. This would be really helpful for websites that are pre-designed and just need color tweaking to change the look quickly.
It would need to be something that would force the updates across both GenerateBlocks Pro and GP Premium.
Global colors would be able to be set in Customizer and be used in Global Styles.
