Rendering:

First we create text effects.
Create a new 450*250px file, create a new layer, and fill it with white. Press T, select the horizontal text mask tool, use a font you like, you can find it elsewhere! Set the font size to be larger, and then type the word Blue

Then feather it, set the radius to 5px, don’t feather it too big! Then set the foreground color #0000CA and background color #E300B6, of course you can also set your own favorite colors. Then execute the "Clouds" filter and press Ctrl+D to deselect.

Go to "Filter" > "Artistic Effects" > "Watercolor" and set the parameters to Brush Detail: 1, Shadow Strength: 0, and Texture: 1.

In fact, I think it would be cooler to choose a good background to show the text effects on it. Start by choosing a background.
Move the background below the text and set the layer mode of the text layer to Multiply.

The effect is as follows.

Create a new layer below the text layer, then select the Brush Tool and set it as shown in the image below.
