I didn't save the .psd file but I tried to make something that looks the same. :)
I use Photoshop CS but this tutorial will probably also work with other programs.
From
This to
Grab your base and resize/crop it down to a 100x100 icon.
Create a new adjustment Brightness/Contrast layer. (Image->Adjustments->Brightness/Contrast)
With the following values:
Brightness: +33
Contrast: +12
Set that layer to screen and change the opacity to 80%.
Create a new adjustment Color Balance layer. (Image->Adjustments->Color Balance)
Use the following values:
Color Levels: -37/-3/+6 set to midtones.
Now the icon looks really washed out.
Create a new adjustment Hue/Saturation layer. (Image->Adjustments->Hue/Saturation)
Use these values:
Hue: 0
Saturation: 44
Lightness: 0
The icon looks still to washed out,
so create a new layer and fill it with #d7d6d5 and set it to Color Burn and set it to 72%.
So we're done with the colouring but for an extra effect I add a dusty texture made by
peoplemachines and set it to screen.
Final result:
Here was the original:
Looks pretty the same right?
I hope this was useful to anyone. :)
