In the case of colorPickerOver, I want to remove the colorpicker borderthickness. I gave the thickness as 0, but it doesn't work.
And I want to fill the Rectangle in the ContentTemplate, but the red top, bottom, left and right gray margins remain.
In the case of color picker under, a split button was created to create a ColorPicker, but it is not synchronized with the button next to it.
And can you delete the arrow buttons?
