Changing that Temp on the Fly

When you're using those lamps and others lights that you, your assistant, or whoever forgot to check for the right temperatures then you need to just do this one thing.  Grab that colored sharpie or colored permanent marker and start coloring those light.  Reason, is that if you color a 6,000K light with a blue marker then you just cooled down that light's temperature by some hundreds or a couple thousands which would then even it out to look more natural, and the same works backwards if the light was cool and you wanted to warm it up some.  This only takes a little bit of time by the way everyone
