I recently interested in it this kind of high contrast and bright colour style. I think it’s really hard to control and sometimes the background will be messy because of the high colour saturation. But I would like to try something else because the colour tone of the Children’s Society project I did before is very simple and low brightness. So I use this style to finish the background design of the HOLE story.
I think the point is, make sure that the scene only has two contrast colour, and set one of the colours is the main colour tone. Then use the colours having the same temperature as the main colour to create things. Because I only use two contrast colour so the hue won’t be too complex.
