To sum cells based on one criteria (for example, green), use the following SUMIF function (three arguments, last argument is the range to sum).

Sumifs
To sum cells based on multiple criteria (for example, circle and red), use the following SUMIFS function (first argument is the range to sum).
General note: in a similar way, you can use the AVERAGEIF to average cells based on one criteria and the AVERAGEIFS function to average cells based on multiple criteria.
