Conditional Formatting Based on Multiple Rules - google-sheets

Question

I'm trying to create a multi rule custom formula for conditional formatting purposes in Google Sheets.
Here is what I want to achieve -
If Deal Size is Small, the deal length cell should be highlighted a specific color based on the criteria -
0-35 Green
35-40 Yellow
40+ Red
If Deal Size is Large, the deal length cell should be highlighted a specific color based on the criteria -
0-45 Green
45-55 Yellow
55+ Red
Here is some sample data -
Date Deal Started
Date Deal Ended
Deal Length
Deal Size
1/13/2023
1/25/2023
12
Small
12/8/2022
1/17/2023
40
Large
11/8/2022
1/9/2023
62
Small
10/7/2022
1/31/2023
116
Large
12/12/2022
1/30/2023
49
Large
I've read some blogs online but haven’t found a solution for what I want to achieve.

Answer 1

0-35 for green and 35-40 for yellow. So what color if exactly 35?
Use 3 custom formulas for conditional formatting. Move = signs where needed. Range in example C2:C7
Green:
=OR(AND(D2="Small",C2>0,C2<35),AND(D2="Large",C2>0,C2<45))
Yellow:
=OR(AND(D2="Small",C2>=35,C2<40),AND(D2="Large",C2>=45,C2<55))
Red:
=OR(AND(D2="Small",C2>=40),AND(D2="Large",C2>=55))
Result:

Answer 2

or you can do it like this too:
green:
=((D2="Small")*(C2>0)*(C2<35))+((D2="Large")*(C2>0)*(C2<45))
yellow:
=((D2="Small")*(C2>=35)*(C2<40))+((D2="Large")*(C2>=45)*(C2<55))
red:
=((D2="Small")*(C2>=40))+((D2="Large")*(C2>=55))
