IME producing artwork that relies on subtle color relationships requires high quality, "full spectrum" illumination. Natural daylight is the obvious canonical option, but of course not always practical.
My studio gets very little natural light, so selecting optimum light sources is crucial. At one time the most practical option was D50 compliant fluorescent tubes, but these were only fairly acceptable.
Situation with LED lamps is also difficult. Even CRI 90 is inadequate, mainly poor red emission and excessive blue radiation. However D50 compliant LED fixtures are available if somewhat more expensive vs. typical LED lamps.
One vendor worth checking out is Waveform Lighting [0]. They offer several types of products with CRI 95 and CRI 99. I've been using their D50 'shop light' for several months and find it very satisfactory.
