Update New settings browser button color after a color has been accepted in the Color Picker

[hernanmd]

Description

The current implementation of the Color Picker feature does not update the color of the "Setting Browser" button after a new color has been selected and accepted. This inconsistency in the user interface can lead to confusion and a poor user experience.

Steps to Reproduce

• Open the New Settings Browser and navigate to the "Text Editing" section.
• Click on any setting displaying a color, for instance, "Selection color" button to open the Color Picker.
• Select a new color from the Color Picker and click "Select".
• Observe that the "Setting Browser" button retains its original color and does not reflect the newly selected color.

Expected Behavior

After selecting and accepting a new color from the Color Picker, the "Setting Browser" button should update its color to match the newly selected color. This visual feedback will provide a consistent and intuitive user experience.
