Measure issue

Hi All,

I have a matrix where rows are different cost types, the column has months from January to December, the values is the amount which is of two types either forecast or invoiced. Filters applied are for "Items" & "Year".

If the amount is invoiced it should be shown green in the matrix for that month and if the amount is forecast it should be shown as blue in the matrix. Now I am facing the issue where in for the items have been invoiced but there is $0.00 occuring in that cell. Invoiced items don't have $0.00 but forecast have now for the previous years like 2020,2021,2022 which is entirely invoiced but some of the items have $0.00 which falls under forecast. I am able to acheive green colour for the previous years for all the values by below measure

If(OR(selectedvalue(itemtype)="Invoiced",c.amount = 0),"Light Green", "Sky Blue")

The issue with the above measure is for year 2023 & 2024 all of it should be blue since it is forecast but $0.00 in 2023 & 2024 is green because of the above measure which is wrong. I want everything to be blue for the 2023 & 2024. Can someone help me modify my measure. It would helpful.
