Ashan,
Please check the original message from the customer.
It seems that Include Anything’s Color Select doesn’t work on WordPress.com.
They’ve tried deactivating plugins and switching the theme.
Perfect! Please re-activate your plugins and the theme.
Thank you for your messages, I am going to assign this ticket to Ashan and he will be able to take it from here and find you a solution. Please allow some time for him to get back to you, we greatly appreciate your patience and thank you for being a eventon customer! Also please disable any IP blocking on your site if there are any.
As a temporary solution, please go to Edit Post and open Developer Console by inspecting an element:

Right click on it and then press Inspect:
Now find this HTML tag and put your color HEX into value:
Update the post.
It should change the color.
