The goal is to highlight numbers in the Numbers sheet based on the numbers in the Update sheet F4:K13. For instance, all numbers in F found in Numbers group would all be colored the same, all numbers in Update sheet column G found in Numbers sheet are colored and so forth. Using different colors for each column in the Update sheet.
The attached sheet has a code that performs the intended purpose but runs way too slow. You can either write your own code or update this code to work faster.
