sumif color cells with same month

[eva cheng]

My file have two columns A - Month B - Amount
I will change the color to red of certain cells in column B
Can I use the sumif function to total column B of those cells with same
month and color red ?

Many thanks

You can't sum by color (is there some criteria you could use, such as
greater than x value?), but you can sum by month like this:
=SUMPRODUCT(--(TEXT(A2:A100,"mmm")="Apr"),B2:B100)
