Neumorphism can be seen as a hybrid style of flat design and skeuomorphism that has been around for a couple of years. Although you don't see too many works using this style today, it is still an excellent resource that deserves to be taken into account and should be on any designer's toolbox. This style can be made in a wide range of apps (including Photoshop). It is also a good idea to know how this effect can be replicated in Illustrator and have it in a vector format in case we need to use it on poster or other larger print formats. So today, I will show you how you can replicate the Neumorphism Style in Illustrator in 10 easy to follow steps.
Open Illustrator and make a new file at any size you want. In this case, I will make mine at 600 x 600 px.
Select the Rectangle Tool (M) and draw a square covering the whole artboard using any color you want. In this case, I will draw mine using #dbe8f1.
Select the Ellipse Tool (L) and click once over the artboard. Set the Width and Height to 240 px and click OK.
With the circle selected, go to Window > Gradient. Select "Linear" under Type, set the Angle to 45º and then set any gradient you want. I will setup mine from #f8fcff to #c5d7e5.
Go to Edit > Copy and then to Edit > Paste in Back. In the top toolbar set the copied circle size to 260 x 260 px.
In the Gradient window, click on the "Reverse Gradient" icon.
With the circle selected, go to Edit > Copy and then to Edit > Paste in Back. In the top toolbar set the copied circle size to 340 x 340 px.
Select the Eyedropper Tool (I) and click once over the background square we did in the Step 2.
Select the 3 circles and go to Object > Blend > Make.
Lastly go to Object > Blend > Blend Options. Set the Spacing to "Specified Distance", the distance to 0,5 px and click OK.
