I've made a macro that defines custom colors. What code will permit me to cutomize the ControlTip that is shown to the user when they have their cursor over each color

Let me explain. I am trying the code a macro where I have defined a blue that we internally call "Blue Pastel". I would like the name "Blue Pastel" to be displayed when the user is in the Background or font color menus and they put the cursor or that said color

Thanks in advance for your help
