Where you can enter a formula and determine if a cell contains a certain value, there is no forumla that can do a similar thing for a certain format.
However, all is not lost. Help is on the way! This is a User Define Function (UDF) that can return a string, reflecting the cell interior color for the colors Red, Blue, Green, Yellow, White, Black, Magenta & Cyan.
Paste it in a Module. It would be good to put it in your PERSONAL.XLS workbook. Then, use it like any other function on your worksheet like this... =IF(WhatInteriorColor(A1)="Red","I got RED!","nada")
Function WhatInteriorColor(rng As Range) As String 'Skip Metzger - 2007 May 29 'this function returns the color of the interior of a given cell ' Select Case rng.Interior.Color Case vbBlack WhatInteriorColor = "Black" Case vbRed WhatInteriorColor = "Red" Case vbGreen WhatInteriorColor = "Green" Case vbYellow WhatInteriorColor = "Yellow" Case vbBlue WhatInteriorColor = "Blue" Case vbMagenta WhatInteriorColor = "Magenta" Case vbCyan WhatInteriorColor = "Cyan" Case Else Select Case rng.Interior.ColorIndex Case 2 WhatInteriorColor = "White" Case xlColorIndexNone WhatInteriorColor = "None" Case Else WhatInteriorColor = "Other" End Select End Select End Function
