That's good. 

Earlier you mentioned that your non-flash light source was too yellow. 

I asked what kind of bulbs you were using, but you haven't responded yet. 

Today, I went on to the Adorama site and found this seties of links ... 
Adorama -> Photo Essentials -> Lamps ... which lists 190 lamps ... most show the color temperature as a Kelvin number. 

You might also want to check  Adorama -> Flash/Lighting ... there you will see 11 categories of lighting equipment ... and you might find something ... aaaaahhhhhh ... interesting.
