Root Cause: The palette preview's text color inherits dynamic colors from the BC pattern, leading to insufficient contrast against some backgrounds. This wasn't a problem in the original design, as the BC pattern was introduced later.
Solution: Set the palette preview text color to textColorPrimary to ensure the text remains legible against a wider range of background colors.

Root cause: The orientation of the gradient drawable follows the view alignment. It should consider the text alignment.
Solution: Use getLayoutDirectionFromLocale# to get the text alignment to
set the correct orientation of the gradient drawable.

Root Cause:
Using the listener to update the UI dynamically might have some time delay.
Solution:
Refactor to another implementation and avoid using the listener to update it.
Additional condition:
Add height restriction in preference to avoid the palette view to cover whole screen.
