Open the image in Photoshop. Go to Image and then to Adjustments. You can balance your colours in two different ways.
Colour balance: When you opt for the colour balance option, you will be prompted to make the changes via three channels: Cyan, magenta, yellow. These three colours can be tweaked to your liking. You will notice that the three channels have inverse colour on the opposite end. This means that when you increase one colour, the same action also decreases its inverse colour.
Hue Saturation: When you click on this, a window opens. The first option on that is Edit, which allows you to choose Master (overall colour) or individual colours like Red, Yellow, Green, Cyan, Blue, Magenta to work on.
Remember that clicking on Hue helps you correct colour by changing the colour palette itself. By using the Saturation option, you can adjust the amount of colours already present, that is, the colours get more or less pronounced. The Lightness option allows you to increase or decrease the darkness of the colour.
