I have a large array that I need to insert some colors into. What is the best way to do this from the inspector?

I want to fill in a large array of colors with my hands. I have a certain number of colors that I want to use. The problem is that setting the color of each cell separately is inconvenient and time-consuming. I would like to know if there is a way to do this:

  • select a color and set it for a cell in one click;
  • select a certain number of cells to fill.
