When you take a photo do you ever think of adjusting the colours or the hue? It’s easily done on a smart phone. You can use so thing called ‘curves’ where you can change all the colours, tones, contrast and dark and light using one tool. You have a curve indicating the colours and by adjusting the curve in different places…. I’ve taken a few screenshots to explain. First take a picture, then go to photo editor.

I don’t know how anyone else’s phone works, but in photo editor if you find the editing button in editor, choose the one for changing colours. The icon has a curve on it. Click on that and you can adjust the levels, you can see them move on the screen. When you like it choose save. You then have an image that looks completely mad, or subtle, or however you like it.
