As Marvin Mattelson advocate it is important to get the right light values. And that is one thing you CAN do in a dim light.

Allan, absolutely!!!!
The question that you have to answer when forming your composition, what color DO you want us see?. What is the mood and feel you're shooting for. Then select the light sources that will facilitate your choice and paint what you see. You are the creator. The key for me is to have ENOUGH full spectrum light = foot candles, at the task to see what I'm doing. And yes it should/must be the same temp. as what is lighting your subject. Consistency. That's why artists used North light before electricity, because it was more consistent throughout the day.
Color perception is subjective. But the technology behind various light sources is not. The above mentioned CRI reference was applied incorrectly to the subject and being that my day job is a commercial lighting and electrical designer/distributor I thought I'd throw some light on the subject.
. CRI is a grade. Think of a 4th grade student who gets a 98% on his science test. Is he a better scientist than my 5th year bio/chem daughter who got a 92% in molecular what ever? Not really related. Doesn't mean the kid's not smart, but it's relative to the class.
I assumed that Marvin, like so many others had been misinformed by a lighting manufacturer who wanted him to buy their expensive lamps. Think about this. If fluorescent light was a good full spectrum light source, why do cosmetic counters, art museums and studio stage designers use halogen? I'm not saying the light Marvin mentions is bad. It's not, but bang for your buck, a Solux 5000K MR16, selling for $8.00 can be placed nicely in a track lighting set up, manipulated with gels, filters and barn doors, to get anything you need. It's dimmable and low harmonic with the right x-former.
I've used fluorescent in the past at home, when I first started painting, but as I woke up and started applying the knowledge from my day job to the problem of task and set-up I realized that the power bill was the least of my worries, when trying to paint at night. Hit the Solux web site for all of the technical blah blah if your head is not swimming enough yet.
