custom colors not applied

[otrsw]

Hi there. Nice component - just checking if the colors method is implemented?
I tested with a simple manually generated chart - the graph generates fine, but if I want to specify custom colors they are not applied

return $this->result([
            'Group 1' => 100,
            'Group 2' => 200,
            'Group 3' => 300,
        ])->colors([
            'Group 1' => 'blue',
            'Group 2' => 'green',
            'Group 3' => 'orange',

        ]);
