Colour transparency issue in formatted columns since in the SP Update

Richard_W_01 You can always select your own color codes to and use them instead of their as shown below:

Go to the advanced mode of the format column

Then add the json format logic and use your own color codes from here:https://htmlcolorcodes.com/

In the below example we have shown how to color code the columns on the basis of value similarly you can use your logic.

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
  "elmType": "div",
  "txtContent": "@currentField",
  "style": {
    "background-color": "=if(@currentField<50, '#F5B7B1', '#82E0AA')"
  }
}

Mark the response appropriately if it help you finding the solution.

Thanks,
