the shade you like, the people at the paint counter can always add white in small increments until it's the exact shade you want...or they can add any other color, for that matter. If it needs to be warmed up a little, they can add yellow, if it needs to be darkened a little, add black. When I painted my living room a shade of "wheat" yellow, my hubby threw a fit because it was "too" yellow and he HATES yellow! ;-) I spent an hour at the paint store with them adding various colors to change the tone and shade. It doesn't cost anything extra and they (usually) know what they're doing when it comes to getting just the "right" color for you. It's only paint, if you decide a year from now that you really don't like coral on the walls. Easily and pretty inexpensively changed. Go for it! :-)
