Hello and we got very colorful results for today. Today we are going to make
stylish minimalistic, but
colorful wallpaper in
Photoshop. Besides that we will great a text part too - meaning that we will try to combine the text part and the background
into 1 single design. So let's go then.

Create single document:

Fill it with black.

But we still need that white too, so create a layer and fill it with white. We need this white to create a brush and that's
all. You can delete it then.
...to create a brush:
Select about this area.

Fill it with black to white gradient: there even no need in creation another layer: just work on one.

Go to
Filters > Artistic > Cutout to divide complex tones.

Define it as a brush:

Select the settings:

Now, I did delete this white layer leaving us with black background. This will be our painting background.
Create a new layer and begin to paint with the brush we've created.
I'll start form yellow

Now little bit of red; I'm still controlling the opacity with pressure on my pen.

...Maybe even some blue can fit here:

When you are done apply motion blur on
90 degrees:

For composition means just transform it just a little bit.

I just can't wait to adjust the colors of this thing.
Tap
Q to enter quick mask. Switch to gradient tool and apply the mask areas of the mask applying the gradient in mask mode.

Tap q again to exit quick mask and see the selection.

Adjust the selected area colors with color balance:

Now I also want to adjust the lower part. So we do have the good selection: just invert it clicking the right mouse button
inside the selection and choosing - invert selection. Moreover further the selection but not much - 2-3 px will be ok.

This time apply hue saturation adjustment.

So our graphic part is ready: the text part is in the way. I will not explain you a lot about the text work: just look
closely and remember that the text should be looking like an object - solid. The entire element should be aligned properly.
It is Just a matter of understanding.

It is just a little dot over there to take your attention on the text. And the smoke trail done with smudge tool.

To be continued.
