Macro to compare colors in cell and type result

[Ssaamirr]

Hello sorry for bad english,

like u see in attachment i have products in cells wich are painted in different colors. I need to compare two numbers of different product, and write result to column "Type D,C,B". If one of two products is without color/white or they are not the same color then result is always "D", if both products/cells have same color and different number then results is "C", if the color and number is the same then result is "B"

Below cell B2 I will write numbers by hand, when I finish and start macro it will compare first cell B2 and B3 and write result to C3, then compare B3 and B4 and write result to C4 and do that until there is any number in column B:B.

Hope u can help me . :)

Tnx
