Conditional Formatting in Excel: All you need to know

This is about visual identification and/or formatting (differentiation) of our data sets based on our questions (conditions), in order to: 

• mark/reveal some data of interest, present them
  
• take some action (e.g. find errors, correct, sort, delete, evaluate), or
• find out some trends and patterns, compare.

Here is the Conditional Formatting main menu (on the left) + More Rules dialog:

COLORS in Cells: How to Get, Set and Use them

It's really easy to color Excel cells, their background, content or borders. We can do it either directly (using Format Cells... or some Font options) or indirectly - using Conditional Formatting in a variety of available ways in the Excel menu.

When it comes to determining (getting) exact codes/names of colors being already used in a worksheet, it can be a bit complicated. And it may happen that you need to know what colors were originally used for background filling of some cells. Well, we can't find it out by using any Excel function or formula. So, practically, we must use macros (VBA codes) to solve such puzzles. E.g., the following code will determine Color Index for background color of cell A2.

Press ALT+F11 keys to display the VBA editing window and enter there this code:

Sub getCellBG()

Dim getC as Integer

getC=Range("A2").Interior.ColorIndex

End Sub
