Okay
I tend to start off with pink because it looks nicer than red
but another good color to start off with is yellow.

Of course use primer because it makes it last longer and look brighter.

So if you start off with pink blend orange then yellow and end with blue. (I suggest a darkerish blue) then take the purple and use it as under liner and blend the pink with purple making fushia. O3o that's my favorite.

If you start with yellow use only yellow green and blue because it looks cute that way

You can go days with using partial rainbows.
Just have fun owo
