Apple

Look at this apple as I am holding it with both of my hands in front of you in the dark cellar dimly lit by the candle on the desk behind me. Study its red color, with shades of light green, attracting the caged creature hidden away by darkness in the corner close to you. Feel its weight by studying through the power of vision in this cellar, ignoring the spiralling staircase going upstairs at the back end wall.
