Understanding Color Temperature

Importance of Color Temperature

Knowing about color temperature is super important. It's all about figuring out the color of different light sources. If you're into photography or cinematography, understanding color temperature is key. Colors are essential for telling your story and getting your message across.

Every color has a specific meaning and conveys a message. Color temperatures can range from cool to warm. Let's dive in to get a better grasp of color temperature.

What is Color Temperature?

Color temperature is all about how warm or cool the light is. Different light sources have different colors. Light comes in various shades, including skin tones.

Since every light is unique, some lights make a scene look warmer, while others make it cooler. Our eyes are pretty amazing as they can adjust to different types of light. Most of the time, we don't even notice the colors. But cameras pick up on every color.

If you take a photo with an orange tint, the temperature will need to be adjusted. In photography, color temperature and white balance are often used interchangeably. The goal is to set the colors so that whites don't look tinted. It's best to adjust the colors around a neutral shade.

Choosing a White Balance

In photography, there's no one-size-fits-all color temperature. It's important to match the color temperature to the scene you're capturing. Color temperature can be a personal choice. Some photographers prefer cooler tones, while others like warmer tones.

Most cameras come with presets for color temperature. The most common presets are Tungsten, Fluorescent, Daylight, Cloudy, Shade, and Flash. Professionals can also adjust the temperature to suit their needs.

If you're unsure about the type of light, using Auto white balance is a good option. It works as a reference point for neutral gray in the scene. The camera uses this reference to set the white balance. However, color adjustments can always be made later on.

Color Temperature Chart

Color temperature is measured in kelvin. Like Celsius, kelvin is a scientific scale that determines how cool or warm the light is. Lower kelvin numbers are considered warm, while higher numbers are considered cool. For example, a sunset is warm, but shade is cool.

To adjust tints, you can make changes in the opposite direction. If the sky has a cool temperature, adding warm color tones can make it look more natural.

Why Color Matters?

In photography and cinematography, colors are crucial for telling a story. Color theory influences everything. Each color sends a message and has meaning according to color theory.

Nowadays, it's easy to change colors using tools. It's best to start with your preferred base colors during a shoot to make editing easier later on.

How to Fix White Balance in Post

If you find that some photos aren't white-balanced correctly, there are different ways to correct the colors. Remember, color correction and color grading are different from working with color temperature.

How to Add Color Highlights

Adding color to lighting can help you create different moods in a single shot. To use these techniques effectively, it's important to understand color temperature. If you want to add warmer or cooler colors to a shot, follow these steps:

Set up your initial lights

Start by setting up your main lights. These lights are essential for creating the desired exposure. Think about whether the scene will be bright or dark, where shadows will fall, and so on.

Set your white balance

In a traditional three-point lighting setup, the main light will determine the white balance. This ensures that the exposure in the shot looks natural and realistic.

Set up colored light sources

Once you have your lighting setup and white balance set, you can add color highlights. Begin by adding small light sources around the white balance color temperature.

You can place light sources below the white balance for warm color accents. For more striking color highlights, place a light source above the white balance. You can use gels to change the color of the light.

Color Temperature and Psychology

Did you know that red is considered warm, while blue is cool? The source of high energy is hot, so it appears blue. But as the energy source cools down, it changes from yellow to orange to red.

Aside from the physics aspect, color temperature is also linked to psychology. We associate colors with certain psychological triggers. Blue is seen as cool because of water, ice, or the sky. On the other hand, red is warm due to fire, sunsets, and warmth.

The Appearance of Color Temperature

The color temperature of light determines how the light source appears. If a light looks red and warm, it has a warmer color temperature ranging from 2000K to 3000K.

On the other hand, cooler color temperatures range from 4000K to 6000K and have more blue light wavelengths. The corresponding light spectrum will have more red light wavelengths for warmer color temperatures.

Role of Color Temperature in Our Lives

Color temperature affects our energy levels and moods. Warm color temperatures evoke feelings of coziness and relaxation, while cool color temperatures increase energy levels. Blue light wavelengths, in particular, make us more alert.

Our eyes are sensitive to blue light, which signals the brain to suppress melatonin, a hormone that regulates sleep. That's why warm lights are preferred for relaxation, while cool lights can keep you awake.

Color Temperature Wavelengths

Every light source has a different color temperature. LED lights offer a full spectrum, Incandescent lights provide warmer light, and fluorescent lights offer both warm and cool color temperatures. Here are the variations in wavelength depending on the light:

1. Light below 2000K gives off a dim glow, like a candle.

2. Light in the 2000-3000K range produces soft, yellow light, ideal for outdoor settings.

3. Light in the 4000-5000K range provides a significant amount of white light, great for offices and workspaces.

4. Light in the 5000-6000K range emits bright blue light, similar to sunlight.

5. Color temperatures above 5000K are less common and are used in situations where intense illumination is needed.


Understanding color temperature is crucial. Color temperatures can range from cool to warm.
