Colour gradient?

[Arten K]

Hi everybody! I would like to make a gradient like this for a kids workshop (to print as a background basically, size around 1x1m). Any idea on how to make this?


I would make it without the cells, anyway my guess is they have been superimposed last, after creating the colours.
Seems fairly easy but I use PS only for retouching from time to time, so I have no idea..
Thank you!

Create a blanc canvas (in this case 3000 x 3000 px) and fill it with white.
Add a blanc layer on top and use a large soft brush to apply the four colors you want (make sure the center of the brush is on each corner and that the colors overlap somewhat.
With that colored layer active apply the filter 'pixelate/mosaic' and make the blocks at your desired size.

Thanks, I'll be trying tonight. Do you have any suggestions on the brush mode? Or should I use normal mode?

Use the normal mode but if you're not happy with the result make the 'white' layer a bit darker and play with the opacity.

ok i tried...kind of. This is the result.

What resolution and DPI should this be for a 1x1 meter print?

If you want to see the 'blocks' you'll have to increase the cell size!
A resolution of 3500 X 3500 px at 300 ppi should be enough to print it to 1 X 1 meter

I tried pixelating it but I prefer it plain. Thanks anyway!

No problem...
