Since your lighting your own kitchen it shouldn't be that much trouble ...look at the existing lightsources ( a central light on the ceiling, a window, some TL lights under the cupboards etc) and mimick them, i.e. analyse what kinda lights they are( spot light, pointlight etc). keep in mind that indoor lights are mostly yellow tinted so change the colortint on the lights, light from outside ( that comes in the kitchen) is a bit more diffuse and tend to give either a blueish or greyish tinted light dependant on the weather if it is very sunny you can add yellowish directional light to mimick the sun
