Colorling - The Wheel

Your eyelids are dragged open by the blinding sun, as you awake from what felt like an eternal slumber. You are in a room you have no recollection of, wearing clothes that feel like sandpaper on your cold body.

Speaking of the cold, it's quite chilly. You should probably find some sort of warmth, but at the moment you can't see much. The sunlight only pierces the curtains a crack, and it is barely enough to see anything more than the vaguest details.

You feel something particularly heavy lying against your chest, and, pulling it out, you find it to be a small stone slab, with a wheel of shining colors inscribed on it.

They seem to invoke a particular emotion in you when you look at them, and you notice yourself heating up when you look at the red, or cooling when you see the faint blue. The yellow inspires a feeling of hope within you, while the purple makes you feel rather pessimistic. Likewise, the green calms you down, feeling at one with the world, and the pink urges you to burst out the door and find the nearest person to embrace.

All these emotions get a little disconcerting, so you put away the slab for now. In the meantime, a way to warm up without becoming horribly angry would be handy.
