Paint colour can’t impact the quality of light which comes into room, because paint isn’t an illuminant. (Maybe super duper neon paint ?)
Paint colour conversely, is affected by the quality of light coming into a room.
You may have more luck partnering paint colour and available light if you think about that light as being either abundant, moderate or dim.
You can have a south facing room with a tiny window.
You can have a north facing room with a whole wall of glass.
Artists choose north facing studios because they often have the more balanced wavelengths of light throughout the day.
In a north facing room light may spike slightly more in the blue spectrum, but it doesn’t mean it is always downright, absolutely and completely blue.
Light in a north facing room tends to glance-on-by and spill in, rather than beam-in like it may in a very open, west facing room with lots of windows, at the end of a summer’s day.
If you do think of orientation at all, rather than abundant, moderate or dim, then consider that north and south have something in common.
In a well-lit south facing room, lots of windows, you may need to think about colours a little stronger than you maybe used to, if you were to use them in more dimly lit areas. Less colourful colours maybe more inclined to bleach-out.
In a dimly lit, possibly north facing room with smaller windows, you also maybe surprised that the walls can take slightly more chromatic colours than in other more moderately lit areas of the home.
So I would first consider colour choices in relation to other fixed elements, like flooring, windows, worktop. Do they have any kind of colour relationship? And then think about how they may work with the available light and adjust colour strength accordingly. After all light changes day to day, season to season,,,
