Photoshop creates dynamic colored lights

This kind of light silk effect can be seen in many designs. It is gorgeous, elegant and dreamy, and makes people feel very comfortable. In fact, the production method is also very simple: first use the pen tool to draw a soft curved path, then stroke the path, and then define it as a brush. Then apply it to the layer, add some layer styles and colors, and the perfect effect will come out.

final effect

1. First create a new document. Here I use the specifications of 1024 X 768px and 72dpi. Use the Paint Bucket Tool (shortcut G) to fill the background layer with black. Alternatively, you can use a darker gradient instead. Click the brush tool (shortcut key B), and then change the brush settings to 1px diameter, white, and 0% hardness (I didn’t understand what it meant at first, but later I found it under the brush panel. The default is 0%, so there is no need to too carefully).

Create a new layer, then select the Pen Tool (shortcut key P), and then make sure the path is selected in the main tool panel. Now start to slightly pull out about 4 points from the left side of the canvas to the right to form a smooth curve, as shown in the picture below. Right-click anywhere in the file, and then select the stroke path (remember to select the brush for the stroke) to make sure the simulate pressure option is selected, then click OK, and finally press the Esc key twice to remove the pen path.

2. Now press the Ctrl key while clicking on the layer where the arc is located. In the layer panel, the surrounding areas of the arc should be selected. Then click on the menu: Edit > Define Brush Preset and define the arc as a brush. You can now hide the layer where the arc is by clicking on the eye in front of the layer in the Layers panel (I just deleted the layer). .Select the brush tool again and click Menu Window>Brush to open the brush settings panel. Select the brush you just created and set it up as shown below.

3. Create a new layer to place our lines. Okay, now we want to use these brushes to create lines in the image. So first drag the mouse in the canvas from left to right until you have an effect similar to the picture below. Why each line is slightly different is because in the brush settings we set their angle jitter and roundness jitter.

4. Now we will make the lines glow. Click on the layer in the Layers panel and select the blending option. Set the layer's shadow and outer glow options as shown below. Note that although our goal is to create a glow effect, we still need a drop shadow effect because we set the blending options to Normal.

5. Right-click this layer and select Duplicate Layer to create an identical layer. Now duplicate the layer and open the Blending Options panel. The only thing we need to change is selecting the gradient in the Outer Glow option to a different rainbow gradient. Because you'll notice there are two different rainbow gradients here, one with a transparent edge and one without.

6. You can now do some blending of the lines in both layers by using the Eraser Brush Tool. A better way is to put these line layers in a new group and then create a Quick Mask Tool to use the Eraser Brush Tool. Tools for painting. If you are satisfied with the current image, you can skip this step and go to the next step.

7. Here I've added some beads to the lines. This can be done using some of the same techniques as in steps 3 to 5, except using a 2px or 3px diameter brush instead of your own created brush.

8. Now create a new layer and select a large soft brush and paint some brightly colored, random shapes by changing its color. Repeat these steps with different colors until you have the result as shown below.

9. Next go to the menu: Render>Blur>Gaussian Blur, use a value around 100px, and then change the layer’s blending mode to Hue. As for the transparency of the layer, you can decide it yourself. Here I used 50% transparency.
