this is one square. to do this, use google docs' drawing editor, pick a shape, and click gradient in the shape fill picker. then press custom gradient, make the gradient you want, then click ok. then click actions, download, and then Scalable Vector Graphics (.svg). then, once it's downloaded, go to scratch and then open the project you want to add your custom gradient to. click add sprite and then import, import the .svg file, then you're done! you've made a complex gradient in scratch! just don't edit the color using the scratch color picker, or you'll have to re-import the file.
