After a quick Google search and scanning a few paragraphs (which admittedly I suppose I should have done first) yes you are correct in that the 'colour temperature' of light does vary by that amount in a day. However, the scale which it is based upon is for a theoretical ideal and does not reflect temperature change in reality when light impinges on a surface. I was reacting to what seemed like you implying there was an actual temperature change that large, which would render the earth a smoldering rock. (To help illustrate why I was 'arrogant and ignorant' in my refusal, the melting temperature of all compositions of glass will be <2000 degrees Celsius, meaning even with an initial temperature of 0 degrees Kelvin you'd still be about 5200 degrees above that with the highest point of your range).
You're correct as I wasn't aware of such a scale but it would have been the same to say that the colour of light changes throughout the day instead of bring up 'colour temperature', a measurement which doesn't explain much to anyone who doesn't know that's just one way of describing colour.
