White balance refers to the process of removing or neutralizing color casts in your images, for example, like taking an image, full of distorted, too-blue colors, and adding warm colors until you balance out the color cast. Most light sources produce a color cast, and a camera captures the subject as it looks in life: sometimes neutral, but sometimes very blue and sometimes very yellow. During white-balancing process, you’re technically adjusting the colors along two spectrums, those being the, blue-yellow spectrum, and the green-magenta spectrum, in general, natural light only requires correction along the blue-yellow spectrum, but certain types of artificial lighting may produce a noticeable color tint, in which case you’ll need to correct for that, too. The bulk of white balancing in photography consists of  color temperature correction. You’re correcting for a cast produced by the color temperature of the light, which lies along the blue-yellow spectrum. White balance is important because, they prevent you from capturing accurate, true colors in a scene. If you want to photograph a beautiful red sunset exactly as it appears to your eye, you’ll need to neutralize any color casts; otherwise, your image won’t match the real-life conditions you experienced, and color casts tend to look bad. They can mess with portrait skin tones, they can create muddy shadows and sickly highlights, and they can create unwanted moods in your photos. Most cameras allow you to adjust your white balance settings before ever taking a photo. You can also do white balancing while editing. You can even enhance your photos using your white-balance, by applying a too-cold white balance to your photos, you can create a somber, moody effect, and by applying a too-warm white balance to your photos, you can create a welcoming, inviting, even nostalgic effect.
