Hello Dhanajaya,
Most likely the colors are missing because the Kendo theme is not loaded properly. As of R1 2023 SP1 (version 2023.1.314) we no longer support the LESS themes, see the release notes.
If before upgrading you had references to a LESS theme, for example:
kendo.common.min.css
kendo.default.min.css
after upgrading, a single kendo SASS theme CSS file should be referenced. The SASS themes naming convention is also different now, for example: default-main.css (previously it was kendo.default-main.min.css).
If you have been using our CDN to reference a SASS theme, there is a difference in the url and in the name of the file (highlighted below) after R1 2023 SP1:
Here's how the reference of the SASS Classic Main theme should look like in version 2023.1.425:
<link rel="stylesheet" href="https://kendo.cdn.telerik.com/themes/6.3.0/classic/classic-main.css">This single reference should be added in place of the old references you used with version 2021.3.1109.
I would also recommend going through the LESS to SASS migration article: https://docs.telerik.com/aspnet-mvc/styles-and-layout/less-themes/less-themes-migration
