Kadence blocks custom colors saved as global variables

[eastriverstudio]

At the moment the additional colors we can save in Kadence Blocks in addition to the global theme do not appear to be saved as global variables like the theme which seems an odd decision.

Surely these would also be better to be saved as global variables like the theme so if any future changes are made they could be update everywhere used. Without this currently it renders the custom colors a little limited in use for the fact I can't update them later globally. This may not be a major issue on small sites, but working on larger site and using these static custom colors could lead to a lot of manual work if they need to change.

Thanks
