Summary: When a color is applied to an element and later deleted from the color panel, the element still displays the old color instead of updating or reverting.

Steps to Reproduce:

1. Apply a custom color from the color panel to an element (e.g., a button or text).
2. Go to the color panel and delete that custom color.
3. Observe the styled element on the canvas.

Actual Result:
The element still visually displays the deleted color.
There is no refresh or update to reflect that the color no longer exists.

Expected Result:
The element should either revert to the default color or visually update to reflect that the assigned color no longer exists.
