change painted brush colour

[jeffers]

Having a confused day with my thinking so how do I / is it possible....I paint on a layer a brush stroke 1 or more. ( in this case I'm using a "lightning brush" to create a storm effect on a pixel image ) which comes out as black or whatever colour was picked in the colour swatch to start.

Can I then go back to that brush pattern and change it from black to red for example. I can't figure it out as seems the colour of the brush is determined and fixed at whatever colour you start with.

You can try adding a Recolour Adjustment to the pixel layer you put the lightning on.
Or you could try using a Colour Overlay Effect on the same layer.

Yes, the color of a pixel brush stroke is set at the time you paint it.

The techniques suggested by GarryP may help you. But note that you need to make sure that you paint on a new pixel layer, so the brush strokes are separate from any other pixels that may be part of the image you're painting on.

A bit annoying as trial and error means creating and deleting a new overlay pixel layer until it looks how I want

Afterthought......when I get the right colour/effect I'm after for the lightning bolt it can be saved as a new brush I suppose. Thanks for replies.
