Solution
The human eye captures white as white, red as red and blue as blue, regardless of whether you are outside under the sun or inside under incandescent lighting. Although this is something that we take for granted, the human eye actually adapts to correct the changes in color under different light sources.
In reality, when light sources vary, colors caught as the reflection of those light sources also vary. For instance, films for cameras that use film are designed to capture the most appropriate coloring outside under the sun. Thus when you take pictures under incandescent or fluorescent lighting without using a flash, the colors in the resulting picture may seem strange.
This camera is equipped with a handy feature called "White Balance" that corrects the changes in color under different light sources, just like the human eye.
This camera is equipped with a feature called "White Balance". This feature corrects the changes in color under different light sources, just like the human eye. One of the white balance settings, "Auto White Balance" (AWB) automatically adjusts to correct the changes in color under different light sources.
The function adjusting the color tone so that white objects look white in the picture is called white balance (WB). Normally, the <AWB> (Auto) setting will obtain the correct white balance.
If natural-looking colors cannot be obtained with <AWB>, you can select the white balance to match the light source or set it manually. For example, when shooting a landscape in sunset, if the color tone is not natural in the <AWB> setting, you may obtain more natural colors by selecting the < 
> (Cloudy, twilight, sunset) setting.
> (Cloudy, twilight, sunset) setting.NOTE
In Basic Zone modes, <AWB> is set automatically.
White Balance

 | Shade | 7000 |
| Cloudy, twilight, sunset | 6000 |
 | Tungsten light | 3200 |
 | White fluorescent light | 4000 |
 | Flash use | Automatically set *2 |
 | Custom | 2000 - 10000 |
 | Color temperature | 2500-10000 *3 |
*2 Applicable with Speedlites having a color temperature transmission function. Otherwise, it will be fixed to approx. 6000K.
*3 The color temperature range may vary slightly for each model.

] (Custom White Balance) enables you to manually set the white balance for a specific light source for better accuracy. Do this procedure under the actual light source to be used. For more information on registering custom white balance, please refer to the instruction manual that came with your camera.

The composition ratio of three primary colors (red, green, and blue) differs depending on the color temperature.
At higher color temperatures, the color becomes bluish, and at lower temperatures, the color becomes reddish. As the color temperature becomes higher, the color changes from red, orange, yellow, white, to blue-white.
For example, if you shoot a white subject under a tungsten lamp, the image becomes reddish; and under fluorescent light, it becomes greenish.
