Colour is an important aspect in visual communication. I think it is the first think that people notice when they are looking at a picture (at least for me, when I scroll through a bunch of pictures on the internet, I most likely will click on the ones with the colour scheme that I like).
Basic element of colour
Hue → ex: red, blue, yellow
Brightness → how light or dark
Saturation → intense or dull
Communicate with colour and colour mood
We can colour to communicate our intention. If we want people to feel relaxed we use soft colour like blue or green, if we want to be aggressive we can use red and so on.
For my project I will use earth tone as my main colour because I think it looks similar to the colour schemes of living condition of my subject.
