Actually the art teacher may have disagreed …….as degrees Kelvin is used to describe color temperature. A warm, yellowish light might be described as having a color temperature of 2700 degrees Kelvin while a bright white light might be described as having a color temperature of 5000 to 6000 degrees Kelvin.

My physical chemistry prof always reminded us, there are no 'degrees kelvin', there are kelvins.

AND, when you shop for replacement light bulbs/lamps (LED or CFL) at Home Depot, Lowes's, or specialty lamp/bulb stores, you definitely need to pay attention to the Kelvin range of what you buy. "Soft white" gives you what could be charitably called "pastel" colors. "Daylight" at the high end of the visible light spectrum gives you just what it says but some (many?) folks consider that uncomfortable. "Bright white" is somewhere in the middle. Personally, I prefer the brightest I can get with my 79 year old eyes, especially when I am reading print or working on my various electronic projects.

So, the color of the insulation determines the temperature of the roof?

Colour determines the temp?? Sure does!
