I should create a vector rectangle filled with a gradient made of 4 colors, one for each corner. I could just find some very generic information about using live blends, but I am not sure that is the best tool and still I was not able to do this. How would you get that in Illustrator exactly? (And secondary in Photoshop?)

Gradient Mesh in Illustrator
- draw a rectangle
- select the Mesh Tool
- click one corner of the rectangle
- apply corner color
- Select the Direct Selection Tool
- Click another corner anchor and apply color
- repeat for remaining corners
There’s no simple, one-click solution for a gradient of that nature.
Shape Layers in Photoshop
For Photoshop, the processes is much more cumbersome and involved and nowhere near as precise.
One method could be to use a separate shape/vector layer for each corner, then a solid filled shape as a base.
You basically set a gradient for each shape:
Then once you have the 4 shapes with Gradients change their blending modes to Darken. You don’t absolutely need that bottom white rectangle I used. But things won’t look quite right without a solid color (preferably white) background behind the gradient shape layers.
Another method for Photoshop could be to simply grab the Gradient Tool, set a color to transparent gradient and then drag from a corner. Repeat for each of the 4 colors. The problem with this method is that each time you drag, the length of the gradient will be different. So, you won’t end up with 4 equal corner gradients. The Vector Layer/Shape Layer method ensures the gradients are all the same length.
In the end, I’d simply generate this in Illustrator and then copy/paste to Photoshop as a Smart Object.
To get the effect you’re looking for in Photoshop, I’d suggest the Sblended add-on. Full disclosure: I wrote it.
Here’s a screenshot of the interface used to create the gradient.
- add two lines by tapping anywhere in the main area
- add two color stops to each line by tapping anywhere on the line
- position the color stops at the corners by dragging
- pick the colors you’d like by double-tapping a color stop
Once you’ve built the effect, you can apply it in the same way as the built-in Gradient Tool – by dragging it across whatever area you want.
