Description

While working with Gutenberg ColorPicker, i noticed an inconsistent behavior when removing the HEX value from input field. If we select any color from picker and if we remove it character by character then it defaults to black but if we choose whole HEX at once and clear then it defaults to whatever previously selected and also HEX value is cleared but color still remains selected in picker which can create confusion for user because HEX value is cleared but still color is showing.

Step-by-step reproduction instructions

1. Select any custom color in the ColorPicker.

2. Focus the HEX input field.

3. Remove the HEX value character by character using backspace.

   • Result: the selected color resets to black.

4. Repeat the test, but this time:

   • Select the full HEX value
   • Delete it in single action
   • Result: the previously selected color remains active
