Hello, Grant,

Thanks for your feedback, we will make sure to add this information in the documentation as well.

I believe that you are asking about the `.k-marquee-color`. This className is responsible for the background-color of the resizing. In kendo-theme-default, the background color defaults to `#ff6358`, while in kendo-theme-bootstrap it defaults to `#1247AC`. The opacity defaults to 0.6 in both cases. Having in mind that these values are default, the color combinations(with the item's background color) will not always work. No specific color is universal to work with all other custom colors.

This is why I used the `.k-marquee-color` for the blue item in the example I sent, to change the background and opacity to match the `SchedulerItem's` blue color.

Long story made short - applying the background color of the custom item via CSS is applied only to this item wrapper. In order for the Scheduler to be able to apply a custom color to all elements related to the item's states, you will need to set the color through the colorField prop.

I hope this was helpful, let us know if you have further questions on this matter.

Hi, Grant,

Thanks for the demo,

Here is an example of the Scheduler, where only the item of id `1` has a different background color:

https://stackblitz.com/edit/react-gcbfeq?file=src%2FApp.js

In order to apply a different background color through the `SchedulerItem`, the resized item background color is changed in `CustomEditItem`. Moreover, the `k-marquee-color` has to be overwritten to display the desired background color of the resize hint. It should only be applied to the item of id 1, and this is why the item is given an additional className `removeResizeBgr`.

On a side note, the easier way to apply colors to the Scheduler's items is to directly bind the desired colors to the `colorField` prop. You can refer the following demo for a sample usage of this approach:

I hope this helps, but please let us know if you have any further questions.
