If you need to design a colorful title or banner or something similar, so that every character or group of characters or digits has a distinct color, then you can find this post helpful. Here are just two simple examples of effects you can achieve:
You can easily produce such effects quickly by entering your text (including also digits) in any cell of your worksheet, selecting the cell, and running the macro listed below. Just remember that if your cell contains just a number it must be formatted as text for this purpose.
The macro can be entered/copied into any VBA module of your workbook. Obviously, it can be modified as needed for your specific needs. Enjoy!
