@mismi,
Also that makes sense, mismi, re looking up, airier.
I admit I've never used a grey blue ceiling with a yellow room - either ivoryish or room color --- but but but, in the house I sold last, the old great bungalow, one room had, besides a murphy bed of redwood, don't get me started, a coved ceiling with a rectangle of wood at the top of the curve. Thus I was playing with the idea of a the given wainscott, the wall color, the whatchallit (I'm having a lapse, the fancy wood at the top of the room, left as wood colored), the cove (new color), the wood rectangle (stripped or not?) and the inner rectangle (a greyish blue?) with the light in the middle.
Never got to it, sold the house with that, er, standing ready to be addressed.
