Copy color effect to other text

[Ofnuts]

Attachment in 1st worked well enough.

On possible technique is to paint the text over with a fade gradient.

• Define a gradient with a light and a dark color* Set the brush dynamics to Color from gradient
  
• Set the fade length on the brush to the average length of a stroke
  
• Set repeat to None or Triangular wave
  
• Alpha lock the text layer
  

Then two ways:

• Manual:
  • Take a  "hard" brush wide enough to cover the stroke width 
    
  • Paint by hand, following the strokes with the mouse
    
• Automatic:
  • Get a path from the text layer (Layer > Text to path)
    
  • Set the brush to some soft brush (about as wide as the strokes)
    
  • Edit > Stroke path using the brush, with Emulate brush dynamics
    

   

When you stroke the path, each calligraphic stroke is actually stroked twice, once along each border because the path follows the outline of the stroke. This is why the soft brush is useful because it makes a nice transition between the two actual strokes.

There is also a third way(*) where you create a middle-line path and stroke it (so each calligraphic stroke is only stroked once)
