Kelvins and light source reference...

 

When I use to shoot Kodachrome in the 60s I used a Gossen Sixticolor to measure the color temperature in Kelvins... the meter allowed me to select the appropriate light balancing filter to match the film... With slide film you really want to nail the white balance.

I recently purchased a used Sixticolor but it turned out to be inaccurate : (   so, still looking for a working unit.

Here is another reference chart that may help...

 1,000  K Candles, oil lamps
 2,000  K Very early sunrise, low effect
 2,500  K Household light bulbs
 3,000  K Studio lights (continuous), photo floods
 4,000  K Clear flashbulbs (now obsolete)
 5,000  K Typical average daylight, electronic flash
 5,500  K The sun at noon
 6,000  K Bright sunshine with clear sky
 7,000  K Slightly overcast sky
 8,000  K Hazy sky
 9,000  K Open shade on clear day
10,000  K Heavily overcast sky
11,000  K Sunless blue skies
20,000+ K Open shade in mountains on a really clear day
