More madness over this stuff....
the match was perfect in store, the match is perfect in natural light... say outside
however, my house is full of those pigtail bulbs... but my room had incandescents when I said all was good, I changed them over to pigtails yesterday (because the others were getting too hot)
now the dermablend looks orange under pigtail light
so at home, where I spend most of my time in makeup, I look orange or heavily tanned in the face/neck... which for some reason, to me, makes me look manly ... but if I walk out on the porch, perfect color... 
the lancome stuff does not suffer from the color shift, but doesnt cover the blue shadow enough... back to square one with 90 bucks less in my pocket 
Aw, nope, you're not back to square one! Keep in mind that a darker tone usually implies better coverage for the same product composition and density, so this can be perfectly normal. If it looks good in natural light then it should be looking near good on most lightings. Keep in mind that makeup *always* is gonna look slightly different under very different and powerful lightings.
To give you and example, the perfect professional TV makeup looks usually way too light and "fake" in natural daylight because TV lights are way too light and powerful and the makeup is intended to look perfect under these specific conditions. That is gonna happen to a certain extent to any existing makeup. Also pro makeup artists recommend doing your makeup under a balanced mix of white/yellow lights: if you do it under too much white lights you're gonna to overcorrect, so if you do it under too many yellow lights you are gonna to undercorrect.
Light tones tend to soften your appearance, and this happens both with skin tones and hair tones (that's why you usually hear that blonde or light browns soften facial features). This is whats gonna happen if you go for a tan session: the darker colour of your skin is gonna tough/chisel your features. This can make your features look a little bit "masculine" but in my opinion and in your case (where lighting is a minimal change) this should not be worrying.
