Step 1 [ chose main color and fill the paper (bottom 1) with the color ] Step 2 [ chose a color (or more) and have it at any opacity but needs to be a low one ] Step 3 [ paint bucket the first layer ] Step 4 [ make a new layer and to the same, move and copy and paste it onto the first layer ] Step 5 [ repeat till you have at least 9 opacitys ] Step 6 [ copy and paste the gradient onto a new layer and repeat step 4 ] Sry if it’s not clear enough

Also make as many layers as u need/want to make the perfect gradient
