Question

How do I determine the color of a cell equal to another, example:
A4 is then C2 is cyan color cyan.
A2 is then C2 orange color is orange.

Answer 1

There is no excel-formula to get you the color of a cell, nor is there one, to set the color of a different one.

However, you can make a function to get the color of a specific cell – or, like in my example, the color of the function-calling cell:

Public Function GetColor()
    Dim rng As Range

    If TypeName(Application.Caller) = "Range" Then
        Set rng = Application.Caller
    End If
    GetColor = rng.Cells.Interior.Color
End Function

Now you might, think, ok then I modify this, just to SET the color too. But no – does not work that way. In order to change a cells color, you would have to use Worksheet_Change event and setup each cell to the long value inside them as their color.

Target.Interior.Color = Target.Value

Would be the line for that, when using Worksheet_Change.

You can of course use ColorIndex as well – just adapt accordingly.
