<p>
The ::color-set signal is emitted when the user selects a color.
When handling this signal, use <a href="GtkColorButton.html#gtk-color-button-get-color"><code class="function">gtk_color_button_get_color()</code></a> and
<a href="GtkColorButton.html#gtk-color-button-get-alpha"><code class="function">gtk_color_button_get_alpha()</code></a> to find out which color was just selected.
</p>
<p>
Note that this signal is only emitted when the <span class="emphasis"><em>user</em></span>
changes the color. If you need to react to programmatic color changes
as well, use the notify::color signal.</p>
