I just lower the opacity of the first colour (50%) then after that i try blending it on the second colour and later on I do the same thing with the second colour over the first colour but the opacity has to be more lower than the first one (15%).
Tbh idk how to explain it in words forgive me for that 😭, it’s actually easy if you try it, I just made it more complicated, that just how I do it.
