Feature request: Ability To Color Code/Shade Columns To Visually Identify Related Columns

As a project manager user of monday.com I ned to be able to color code/shade columns so that I can easily identify related groups of columns.

In more detail: If the first 3 columns are related to step 1 in a workflow, the next 3 columns are related to step 2 in the workflow, the next 3 columns are about step 3, etc, etc, it would be very useful to be able to shade/color the top textbox of each column (where the column name is) so that we can easily visually distinguish the groups.
