Led Settings

4 Color Gradient: Unchecked ( we will only use 2 )

Gradient Start Color: #0093f4
Gradient End Color: #00bcff
Gradient Start Color 2: #cccccc
Gradient End Color 2: #ffffff

Note on colors: avoid the 2 start colors being at maximum brightness. That will cause some artifacting in the background image ( as its a jpg ) to become visible.

Note #2 on colors: as the background is pretty much desaturated, and color combination will work pretty good.

Opacity: 100
Peak Opacity: 100

Orientation: Bottom

Size Ratio: 2

Adjust Amplitude: 80 ( just lowering it a bit to not have it max out as often)

Smoothing Factor: Low ( this is optional, but by the looks of the screenshot i used a bit of smoothing .. smoothing tries to smooth out height differences between neighbouring bars )

Other
This is the trick for this wallpaper. It will avoid lighting up the black foreground at the bottom making it look as if it falls behind it.

Blend Mode: "Color-Dodge" ( but multiply, overlay, darken, color-burn, color all work too and give slightly different effects. )


Adjust to position
Now we have 2 systems. This is to demonstrate the new system.
