do a sorta blue light blue gradient, or purple and pink
I tried to make a visual explanation to this. Thanks to Musescore and Windows Paint, the result is highly appealing from a visual point of view.

What they did was draw the thing they wanted but like 1 out of 4 half’s and then keep doing that till it was 4 out of 4 paintings and there you go it’s called a diagonal form of art!
You can use this to help! Good luck :)
