+## Colormap Button
+
+The `Colormap Button` is a custom widget that displays the current colormap and, upon clicking, shows a nested menu for selecting a different colormap. It integrates the `ColorMapMenu` from `pyqtgraph`, providing an intuitive and interactive way for users to choose colormaps within the GUI.
+
+**Key Features:**
+- **Current Colormap Display**: Shows the name and a gradient icon of the current colormap directly on the button.
+- **Nested Menu Selection**: Offers a nested menu with categorized colormaps, making it easy to find and select the desired colormap.
+- **Signal Emission**: Emits a signal when the colormap changes, providing the new colormap name as a string.
+- **Qt Designer Integration**: Exposes properties and signals to be used within Qt Designer, allowing for customization within the designer interface.
+- **Resizable and Styled**: Features adjustable size policies and styles to match the look and feel of standard `QPushButton` widgets, including rounded edges.
