Imagine you have a bunch of different colored crayons to draw a picture with. But sometimes, when you look at your picture, it looks kinda weird. Maybe the blue sky looks too green or the red apple looks more like a pink apple. This happens because the colors in your picture are not balanced correctly. Just like how you need to mix different colors of paint to get the exact color you want, you also need to balance the colors in your picture to make it look right.
Color balance is like a magic trick that can fix the colors in your picture. It's all about making sure that the colors in your picture look natural and the way they should. Different light sources, like sunlight or indoor lights, can make the colors in your picture look different. So, color balance helps to make sure that the colors in your picture always look natural, no matter what kind of light you are using.
It's like when you pile up blocks to build a tower. You need to make sure that each block is in the right place and that the tower doesn't lean too much to one side. Similarly, when you adjust the color balance in your picture, you need to make sure that each color is in the right place and that the colors don't look too strong or too weak.
So, to sum it up, color balance is all about making sure that the colors in your picture look natural and balanced, just like how you balance blocks to build a tower.
