If you are using a "Site Editor" theme and have the Gutenberg plugin activated, then all GenerateBlocks blocks show both your custom colours AND the default block editor colours. This does not happen in other blocks, so it seems like this might be a bug that could be exposed when latest version of Gutenberg moves into core. It might however just be an anomaly that only ever happens with Gutenberg active. :) But it's the latter, it would be nice to have it fixed, just lower priority.
Steps to reproduce
Activate a Site Editor theme, such as 2024.
Activate Gutenberg Plugin (tested with v17.6.5)
Edit a page and change colours on a core block then on the same page try that with a GenerateBlocks block.
Expected behavior
Only your theme registered colours should be displayed as an option.
