Since I don't have a quantified system for color temperature, I have to invent the wheel myself. I wrote myself a tech note as the following. (If the terms are too techie to you, please ignore them at this moment, I will share them again with more understandable words in the future after I get all bugs removed).
I want to establish an absolute color temperature scale. Every color should be specified by a value T for its temperature. The range of T is from 0 (the coolest) to 100 (the warmest). In the HSV color system, I assume the value (i.e. grey scale) change does not affect the color temperature. I also assume the color of Red-Orange (30, 100) is the warmest, and its complementary Blue-Cyan (210, 100) is the coolest. The the temperature T of any color (H, S) can be calculated by the following formula:
T = 50 + (S/2) cos (H - Hh), where Hh = 30 is the hue value of the warmest color.
The image above is an example of the calculated temperature of 12 selected colors. I hope they make sense.
