Excel VBA Custom Function to Get RGB Color

RGB is a VBA Property that can set RGB color. Usually Property comes in a pair, one Method is to Set Property and another is Get Property. However, RGB does not seem to have the Get Method, therefore you cannot get the RGB color directly.

To get the RGB Color, we need to make use Interior.Color Property to get Interior Color code, which is a sum of RGB color with some calculations (see below). After getting the Interior Code, we can convert to RGB color using the below formula

Interior Color = red+ green * 256 + blue * 256 ^ 2

Note carefully that if a Cell is colorless (no color), Interior.Color would return value 16777215, which is also the white color code.
