Is the a way that i can use a custom background color and text color for my info
Thank you for reaching out to us.
Unfortunately, Custom colors are still not supported on Info ShortPoint Background.
But you can change the text color easily by using the SharePoint editor, See the following screen recording for example.
However, if you are comfortable with writing some CSS, you can almost do anything you want using the Class attribute that can be found on any ShortPoint element, you can refer to the following article to know more about how you can customize any ShortPoint using the Class attribute and with a Custom CSS file that can be uploaded into the Change the Look ShortPoint Dashboard Page.
