How to determine and identify the background color index of cells in Excel?

When you receive a sheet with multiple colorful cells as below screenshot shown, in some cases, you may want to identify the background color index of these color cells. There is no built-in feature that can determine the color index of a cell, but, in this article, I introduce some VBA codes to solve this job in Excel quickly.

Identify the color of cell with VBA


Identify the color of cell with VBA

Do as following steps to determine the color of the cell by VBA.

1. Press Alt + F11 keys to enable the Microsoft Visual Basic for Application window.
doc determine color index 2

2. Click Insert > Module to open a new Module and paste below VBA code to the blank script. See screenshot:

VBA: Get traditional hex code of cell

Function getRGB1(FCell As Range) As String
'UpdatebyExtendoffice20170714
    Dim xColor As String
    xColor = CStr(FCell.Interior.Color)
    xColor = Right("000000" & Hex(xColor), 6)
    getRGB1 = Right(xColor, 2) & Mid(xColor, 3, 2) & Left(xColor, 2)
End Function
doc determine color index 3
doc determine color index 4

3. Save the code and close the VBA window. Select a blank cell next to the colored cell, type this formula, =getRGB1(A16), then drag the autofill handle over the cells you want to use. See screenshot:

doc determine color index 5
doc determine color index 6

Tip: there are some other codes can identify the color index of cell.

1. VBA: Decimal value for each code

Function getRGB2(FCell As Range) As String
   'UpdatebyExtendoffice20170714  
    Dim xColor As Long
    Dim R As Long, G As Long, B As Long
    xColor = FCell.Interior.Color
    R = xColor Mod 256
    G = (xColor \ 256) Mod 256
    B = (xColor \ 65536) Mod 256
    getRGB2 = "R=" & R & ", G=" & G & ", B=" & B
End Function

Result:
doc determine color index 7

2. VBA: Decimal values

Function getRGB3(FCell As Range, Optional Opt As Integer = 0) As Long
 'UpdatebyExtendoffice20170714
    Dim xColor As Long
    Dim R As Long, G As Long, B As Long
    xColor = FCell.Interior.Color
    R = xColor Mod 256
    G = (xColor \ 256) Mod 256
    B = (xColor \ 65536) Mod 256
    Select Case Opt
        Case 1
            getRGB3 = R
        Case 2
            getRGB3 = G
        Case 3
            getRGB3 = B
        Case Else
            getRGB3 = xColor
    End Select
End Function

Result:
doc determine color index 8

Goededag,

Graag wil ik vragen waarom deze aanpak niet werkt met cellen die voorwaardelijk opgemaakt zijn!?
Alle codes die ik kan vinden geven allemaal de kleur "geen opvulling" als resultaat terug op de functies.

Hoop van jullie te horen!

I'm sorry, the site translates by itself...

I'm wondering why this doesnt work with colored cells using conditional formatting.
All programs on this page give a "blank" result, so no color at all even though the cell is colored.
If I color the cell myself instead of conditional formatting I get the right result back but i need the conditional formatting too!

Hope to hear from you!
