TYPO3 Core

I have a TCA configuration for a field named color.

My config looks like this:

'color' => [
'label' => 'input_34 renderType colorbox',
'config' => [
'type' => 'input',
'renderType' => 'colorpicker',
'size' => 10,
],
],

In the backend it gets rendered like this:

When i enter the hash value with my keyboard, the color appears on the left side, but if i focus the input box, no colorpicker is shown.
