Try to edit color manually in preview configuration.
HellŠ¾ Fernando,
Thank you for the example.
Setting the tabindex attribute traps the focus inside the modal, as per this Stackoverflow thread. In order to be able to focus the ColorPicker input, either remove the tabindex attribute or use the Kendo Dialog/Window component, where the issue is not reproduced.
I hope I was helpful. Let me know if you have any further questions.
Regards,
Martin
