Hey @meteyou - I've reviewed your changes - here's some feedback:

Overall Comments:

• Please provide more context in the PR description about the specific issue this change is addressing and how it resolves the problem with the color picker for PCA9632.
• Consider adding a comment in the code to explain why we're now using the entire color_order array if the first element is falsy. This will help future maintainers understand the rationale behind this change.
• Be cautious about potential side effects of using the entire color_order array. Ensure that this change doesn't break any assumptions in other parts of the code that might expect color_order to be a single character. Consider adding type checks or assertions if necessary.
