Hi @Mazwen_Bidin ,
Welcome to Airtable Community!
Im assuming here that you want a running sum? This is not something that you can do in Airtable directly (you can use scripts to do so). BUT, another option that I find handy is making the status field a linked field type with the different statuses being options in this other table. In this new table you can use Rollup function to sum all the values you need.
You can use the Color option for that based on a condition. But this puts a color beside the primary field of the record, it doesn’t color the whole record (which is not something that Airtable does).
Hope this was helpful
BR,
