Wilting orchid flowers and reddish leaves... help?

[orangemetaphor]

I bought this plant not too long ago (less than a week) and it's my first orchid.

My dad put it on the porch (All day) while I was away for a day. And watered it.

The petals are drooping and some of them are drying up!
The leaves have a reddish hue to the tips and moreso on the underside

I don't know if it needs more light- less light- I'm just not sure! I really don't want it to die.
I've included some pictures. Might help.
