stairway to heaven

as part of the backyard makeovers, i am painting the creepy indoor staircase from my apartment to the shared yard. i want something fun and refreshing...or ironic and cheeky.

kinda love this idea...but only about 1% of my visitors would get it. mabe just a different colour on each step?

or an ode to my hard-partying ways...imagine the crazy effect this would have on the walls when the light bounces off them?

the more sensible side of me thinks this would be easiest:

and if it wasn't a winding staircase, this would be ideal!
