I want to create a gradient background like the background in the image below:
I have tried the solution in this post but the result is not satisfying. As it can be seen in this picture, it seems that two radial gradient are applied together, if I reduce the number of colors(as it was suggested in the mentioned solution) I will have something like this:
which has curved boundaries for each color, But in the desired image the colors should be bounded by a linear grid. If I change the radial gradient to a linear one, an other problem would occur since the colors should be brighter in some areas in the radial fashion.
As it can be seen in the original picture, its like a gradient modifier is applied then the pixels of the image got enlarged! I have tried several other solutions(including drawing from scratch and it worked!) but I have yet to find an easy solution for this problem.
