The Sun closely approximates a black-body radiator. The effective temperature, defined by the total radiative power per square unit, is 5,772 K. [12] The color temperature of sunlight above the atmosphere is about 5,900 K.
[13] The Sun may appear red, orange, yellow, or white from Earth, depending on its position in the sky. The changing color of the Sun over the course of the day is mainly a. Discover what is Kelvin and light color temperature chart and how warm and cool lights influence the mood, functionality, and visual appeal of our surroundings.

We all know that the standard light source is actually the reference sunlight spectral energy distribution at different times, because the spectral energy distribution has been changing at different times, so the color temperature of the sun is also changing. Let's study the color temperature of sunlight at various times! The color temperature change of sunlight indicates: Sunrise and sunset.
See how to use the Kelvin scale and color temperature chart effectively. Learn to gauge light warmth or coolness in this informative guide. The Kelvin color temperature scale is used to describe the way various light temperatures appear visually.
Understand what these mean so you can make the best lighting choices. Figure 1 - Color Temperature The color of the sun can be measured using Color Temperature, which is a mapping of colors to a reference called a black body radiator. The black body radiator is only theoretical and does not exist but heating a piece of iron would be very similar.
We use the Kelvin temperature scale for this measurement. Figure 2 shows an iron bar that is heated to high. The color temperature of natural light changes throughout the day, depending on the angle of the sun.
At midday, the sun's color temperature might be around 6,000K, which is very bright and bluish. A good point of reference is that the sun at mid-day measure 5780 Kelvin. If you look at that on the scale of color temperatures, that is already getting into the bluish range.
So, what you perceive to be white light actually has a bit of a blue tint. Typical household lamps use bulbs in the 2000-3000 Kelvin range, and you probably consider them to be white as well. A candle registers at 1900K.
Kelvin color temperature is a way to measure the color of light emitted by a light source. It is measured on the Kelvin scale, which ranges from warm colors like red and orange at lower temperatures to cool colors like blue and white at higher temperatures.
