I am looking for a way to retrieve the array of color objects you can set in the theme using add_theme_support('editor-color-palette', [...]);
Somehow I cannot find any information in the documentation on how to retrieve the theme colors inside a custom block.
<ColorPalette
    onChange={ value => onChange(index, 'color', value) }
/>
I need the array of colors inside the onChange callback to convert a hex color to the slug color name I have set inside php using the function getColorObjectByColorValue(themeColorsArray, callbackValueHexColor).
Just for future readers, thanks for the answer @tobiasegli
 <ColorPalette
    colors={wp.data.select( "core/editor" ).getEditorSettings().colors }
    label={'bg color'}
    value={ color }
    onChange={ ( color ) => setState( { color } ) }
    />
