How to make colors change in a chosen sequence

Not sure if this has been asked before but i couldnt find much, it seems simple enough but nothing comes to my mind.

The idea is to have a couple of sprites/buttons.

A blank sprite (which will change colors) and colors

For example

BLUE RED GREEN (colors i can choose)

i decide to click in order

BLUE, BLUE, GREEN, RED

and then every x seconds sprite changes colors in the same chosen order

so thats it, any help would be much appreaciated. Thanks

There are many ways to do it. I made something for you here using an array, something like this to start with?
